5 Words for Complex Problems
Master convoluted, labyrinthine, tortuous, intricate, and multifaceted for CAT, GRE, and GMAT reading comprehension
Complexity has a reputation problem. We reach for the same cluster of words — complex, complicated, difficult — and treat them as interchangeable. But the five words in this post are not interchangeable. Three of them describe complexity as a failure: something that has become tangled, twisted, or impossibly difficult to navigate through its own bad design. Two of them describe complexity as an achievement: the rich, layered difficulty of something that genuinely contains many dimensions and rewards careful attention. Mixing them up in an exam context doesn’t just cost you vocabulary points — it tells the examiner you’ve misread the author’s attitude entirely.
These complexity vocabulary words are particularly common in RC passages that evaluate policies, arguments, bureaucratic systems, works of art, or natural phenomena. Each of these five words signals something specific about what kind of complex the subject is, and whether the author regards that complexity as a problem to be solved or a quality to be appreciated. Knowing which is which is the difference between a correct tone answer and a near-miss.
For CAT, GRE, and GMAT test-takers, this set connects directly to the broader vocabulary of how difficulty, structure, and quality are described in analytical passages. These five words are among the most commonly tested complexity terms precisely because their tonal implications are so easily confused.
🎯 What You’ll Learn in This Article
- Convoluted — needlessly complex and tangled; difficult to follow through its own excess; almost always a criticism

- Tortuous — full of twists and turns; excessively winding and complex in a way that hinders progress; rarely a compliment
- Intricate — having many carefully interrelated parts; complex in a detailed and admirable way; typically positive
- Multifaceted — having many different aspects or dimensions; complex through its richness and variety; typically positive
5 Words for Complex Problems
Three words that criticise complexity as failure, two that praise it as achievement — and the tonal distinctions that separate them
Convoluted
Extremely complex and difficult to follow; twisted back on itself in a way that obscures rather than illuminates
Convoluted is almost always a criticism. It comes from the Latin convolutus (rolled together), and the image is apt: something convoluted has been folded back on itself so many times that it’s become impossible to unravel. The word describes complexity that serves no purpose other than to confuse — a convoluted argument doesn’t become richer through its complexity, only harder to follow. In RC passages, when an author calls something convoluted, expect their overall stance to be critical or dismissive. The word is a structural flag: this thing has failed because it couldn’t or wouldn’t be clear. The key distinction from intricate: both describe systems or arguments with many parts, but convoluted criticises them for tangling and obscuring, while intricate praises them for precision and admirable design. This is the most exam-critical pairing in this set.
Where you’ll encounter it: Critical reviews of arguments or writing, editorial commentary on bureaucratic or legal systems, passages where a writer is attacking something for unnecessary complexity
“The tax code’s convoluted rebate mechanism — requiring applicants to submit separate claims to three departments, each using incompatible software — defeated the purpose of the relief it had been designed to provide.”
💡 Reader’s Insight: Convoluted is the word for complexity-as-failure. When you see it, the author is not marvelling at richness or depth — they are criticising bad design, poor writing, or needless obfuscation. It is a reliable signal of a negative authorial stance toward the thing described. Look for language of defeat, frustration, or structural incoherence nearby.
Convoluted complexity has collapsed under its own weight. But there’s a different kind of overwhelming complexity — one that doesn’t collapse but sprawls, extending in all directions until the person inside it can no longer find their way out. For that kind of complexity, English borrowed one of history’s most enduring images.
Labyrinthine
Resembling a labyrinth; extraordinarily complex, intricate, and difficult to navigate or find one’s way through
Labyrinthine takes its meaning directly from the Labyrinth of Greek mythology — the maze built for the Minotaur, from which escape was nearly impossible. When a writer reaches for this word, they’re evoking that same quality of overwhelming, disorienting complexity: something so vast and intricate that navigating it feels impossible. Unlike convoluted, which primarily criticises bad structure, labyrinthine can also convey a note of awe at the sheer scale of the complexity involved. A labyrinthine bureaucracy may be frustrating, but the word also acknowledges its enormity. In RC passages, context will tell you whether the tone is primarily critical, awe-struck, or both. The key distinction from tortuous: labyrinthine focuses on the maze-like scale (people get lost in it); tortuous focuses on the winding path (the journey exhausts through constant redirection).
Where you’ll encounter it: Descriptions of bureaucratic systems, complex legal or regulatory structures, intricate political situations, dense historical narratives, passages evoking overwhelming scale and intricacy
“The labyrinthine permit process for coastal construction — spanning federal, state, and municipal jurisdictions, with overlapping and sometimes contradictory requirements at each level — had effectively halted development for nearly a decade.”
💡 Reader’s Insight: Labyrinthine says: this is so complex that people get lost in it. Where convoluted focuses on tangled structure, labyrinthine focuses on the navigational challenge — the sense that even a determined person might wander indefinitely without finding the exit. Watch for it in passages about systems or processes that seem designed to frustrate rather than serve, especially when the scale or reach of the system is being emphasised.

Labyrinthine complexity is overwhelming in its extent. There’s a related word that captures a different dimension of the same territory — complexity not as a sprawling maze but as a relentlessly winding path that keeps bending away from where you want to go.
Tortuous
Full of twists, turns, and bends; excessively winding and complex in a way that makes progress slow and difficult
Tortuous comes from the Latin tortuosus (full of twists) — the same root that gives us torture, and the physical image of being twisted is present in both. A tortuous path isn’t just long; it’s constantly bending away from its destination. A tortuous argument doesn’t proceed directly; it detours, doubles back, and makes the reader fight for every yard of progress. Like convoluted, tortuous typically describes complexity as a flaw — but with a specifically temporal dimension: something tortuous is exhausting because of how long it takes and how many turns it requires. It is the word for complexity that wears you down. The key distinction from labyrinthine: labyrinthine describes scale (so vast people get lost); tortuous describes the journey (so winding progress is constantly impeded).
Where you’ll encounter it: Descriptions of legal processes, political negotiations, mountain roads or river routes, arguments that take unnecessarily indirect paths to their conclusions, any passage evoking a long and winding struggle
“After three years of tortuous negotiations — punctuated by walkouts, counter-proposals, and the replacement of two chief negotiators — both sides emerged with an agreement that satisfied neither fully but that both could live with.”
💡 Reader’s Insight: Tortuous is the word for complexity that punishes progress. When a passage describes a process or argument as tortuous, the author is emphasising the exhausting, winding nature of the experience — not just that it was complicated, but that getting through it required sustained effort against constant redirection. Look for the temporal signals: rounds, collapses, detours, restarts — the journey itself is the story.

So far, all three words have described complexity as a problem — something that tangles, overwhelms, or exhausts. But complexity is not always a failure. Sometimes it is the very quality that makes something valuable, beautiful, or worth studying closely. That is where our next word steps in.
Intricate
Having many small, carefully interrelated parts; complex in a way that is detailed, precise, and often admirable
Intricate is complexity worn as a compliment. It comes from the Latin intricatus (entangled, perplexed), but in modern English the word has shed its negative connotations almost entirely. An intricate watch mechanism, an intricate legal argument, an intricate ecosystem — all of these are complex, but the complexity is designed, purposeful, and admirable. Writers choose intricate when they want to acknowledge that something requires careful attention and rewards close study. In RC passages, intricate typically signals an approving or admiring authorial stance: the complexity on display is a virtue, not a failure. The critical exam pairing: convoluted vs intricate — both describe systems with many interrelated parts, but convoluted criticises for obscuring, intricate praises for precision. The tone of the surrounding passage will confirm which applies.
Where you’ll encounter it: Descriptions of craftsmanship, natural systems, well-constructed arguments, detailed plans or mechanisms, literary analysis praising structural sophistication
“The intricate system of checks and balances built into the constitution — with each branch of government holding specific powers over the others — was designed precisely to prevent the concentration of authority that the founders had experienced under colonial rule.”
💡 Reader’s Insight: Intricate is the signal that complexity has been mastered rather than surrendered to. When a passage describes something as intricate, the author is inviting admiration for its careful design or natural sophistication. It is the positive pole of this word set — complexity as achievement. The surrounding language will typically confirm the admiration: words like “precisely,” “carefully,” “designed,” and “skillfully” are fellow-travellers of intricate.
Intricate describes complexity in the structure of a thing — its many carefully related parts. But some subjects are complex not because of their internal structure but because of the sheer number of dimensions they encompass. That kind of complexity, one that stretches outward rather than inward, belongs to our final word.
Multifaceted
Having many different aspects, dimensions, or faces; complex through richness and variety rather than through tangle or confusion
Multifaceted is the vocabulary of intellectual honesty about complexity. Like a cut gemstone with many faces, a multifaceted subject reflects differently depending on the angle from which you approach it. The word doesn’t imply that the subject is difficult to navigate — it implies that it requires multiple perspectives to understand fully. A multifaceted problem resists a single solution; a multifaceted argument acknowledges competing considerations rather than collapsing them into one. In RC passages, multifaceted typically signals an author who is being rigorous and fair, acknowledging that their subject is genuinely complex rather than reducible to a simple narrative. KEY DISTINCTION from intricate: intricate describes internal structural complexity (many carefully interrelated parts); multifaceted describes outward dimensionality (many different perspectives or aspects that resist a single frame).
Where you’ll encounter it: Academic and policy writing, profiles of complex individuals or issues, any passage resisting oversimplification of a topic that genuinely contains many angles
“Climate change is a multifaceted crisis: simultaneously a scientific problem, an economic challenge, a question of intergenerational justice, and a test of international cooperation — each dimension demanding its own set of expertise and tools.”
💡 Reader’s Insight: Multifaceted is the word for complexity that rewards multiple perspectives rather than requiring you to navigate a tangle. When an author calls something multifaceted, they’re committing to treating it seriously — acknowledging its many dimensions rather than forcing it into a simple frame. It signals intellectual rigour, not confusion. The presence of lists of distinct dimensions (“simultaneously a scientific problem, an economic challenge, a question of…”) is the classic multifaceted signal.

How These Words Work Together
These five words all describe complexity, but they occupy strikingly different positions on the spectrum from criticism to praise — and they describe different kinds of complex. The most important distinction for exam purposes is tonal: three of these words are almost always critical, and two are almost always positive. Convoluted is complexity as structural failure — bad design that tangles and obscures. Labyrinthine is complexity as overwhelming scale — so vast that navigating it becomes impossible. Tortuous is complexity as winding process — exhausting through constant redirection. Intricate is complexity as purposeful achievement — many carefully interrelated parts working in concert. Multifaceted is complexity as richness of dimension — many perspectives required, none sufficient alone.
The critical exam pair is convoluted vs intricate — both describe systems or arguments with many interrelated parts, but convoluted criticises them for tangling and obscuring, while intricate praises them for precision and design. Getting this distinction right will resolve a significant proportion of tone and inference questions involving complexity vocabulary. The secondary pair is labyrinthine vs tortuous: both are critical, but labyrinthine emphasises scale (getting lost), while tortuous emphasises the winding journey (being exhausted).
Why This Vocabulary Matters
The critical insight from this word set is one worth carrying into every RC passage you read: complexity words are not synonyms. They describe different kinds of complexity and carry different tonal signals — and on competitive exams, those differences are exactly what the questions test.
When you encounter any of these words in a passage, two questions should immediately trigger: Is the author criticising or appreciating this complexity? And what specific kind of complex is this — structural failure, navigational nightmare, winding process, admirable craftsmanship, or richness of dimension? Answer those two questions and most tone, inference, and vocabulary-in-context questions this word group generates will resolve cleanly.
