TOEIC Link Part 5: turbid versus turgid
Turbid and turgid are separated by a single letter, and both carry a negative tone, yet they describe unrelated faults. Turbid means cloudy, muddy, or unclear, especially of a liquid, and figuratively confused or muddled. Turgid means swollen or distended, and of language, pompous, inflated, and tedious. Part 5 rewards you for asking whether the blank describes something murky and cloudy or something swollen or overblown. For the wider set of look-alike traps, start with the commonly confused word pairs master index.
The core rule: cloudy versus swollen
- turbid (adjective) = cloudy, muddy, not clear; figuratively, confused or muddled. Heavy rain left the reservoir water turbid for days. It answers is this cloudy, murky, or hard to see through? Anchor it with turbid → disturbed sediment → muddy water; think of perturbed, stirred up and unclear.
- turgid (adjective) = swollen or distended; of writing or speech, pompous and overblown. The report was so turgid that few managers finished it. It answers is this swollen, or inflated and tedious? Anchor it with turgid → the g is for "grandiose" — turgid prose is puffed up with big words that say little.
A quick anchor: turbid = cloudy, muddy; turgid = swollen, inflated (pompous). A river or a solution can be turbid; a swollen limb, or a long-winded, self-important document, is turgid.
Why Part 5 likes this pair
The two words differ by one letter and both sound formal and unfavorable, so the wrong option passes a quick glance. The item is decided by meaning: cloudiness or murkiness points to turbid, while swelling or inflated, pompous style points to turgid.
Environmental inspectors sampled the __ runoff flowing from the construction site.
The blank describes cloudy, muddy water, so it needs turbid.
Reviewers criticized the proposal's __ prose, which buried a simple idea in jargon.
The blank describes overblown, inflated writing, so it needs turgid.
Spotting the clue
Check whether the blank describes murkiness or swelling and inflated style:
- Is the word about cloudy, muddy, or unclear liquid, or a muddled situation? → choose turbid (turbid water, a turbid mixture, turbid thinking).
- Is the word about swollen tissue, or pompous, overblown language? → choose turgid (turgid prose, a turgid report, turgid tissue).
A quick test: can you replace the word with "muddy" or "cloudy"? Then it is turbid. Can you replace it with "swollen" or "overblown"? Then it is turgid. In TOEIC business scenarios, turbid appears in contexts of water quality, samples, and unclear situations, while turgid shows up when a document, a memo, or a presentation is being criticized for being long-winded and inflated. Watch the surrounding nouns: water, liquid, and runoff pull toward turbid, while prose, report, and style pull toward turgid.
