TOEIC Link Part 5: moot versus mute
Moot and mute look and sound close enough that writers routinely reach for the wrong one, yet they carry unrelated meanings. Moot is chiefly an adjective meaning no longer relevant or worth arguing because the situation has changed (as in a moot point). Mute is an adjective meaning silent or unable to speak and a verb meaning to turn off or soften a sound. Part 5 drops one into a sentence where the vowels tempt you, so it checks whether the blank means no longer worth debating or silent / soundless. For the wider set of look-alike traps, start with the commonly confused word pairs master index.
The core rule: irrelevant versus silent
- moot = no longer relevant, already settled by circumstances (adjective). Once the contract expired, the dispute became moot. / Whether to expand is a moot question now that funding fell through. It answers still worth arguing? — and the answer is no. Link moot to irrelevant and academic: a moot point has no practical effect on the outcome.
- mute = silent, or to turn off sound (adjective or verb). He stayed mute during the entire meeting. / Please mute your microphone when you are not speaking. It answers making sound or not? Link mute to silent and quiet: to mute something is to stop its sound.
The vowels carry a small hook: moot has the double o of a debate that has gone cold and no longer matters, while mute has the u of a muffled, silenced sound. If the blank describes a point that no longer matters, it is moot; if it describes silence or turning off sound, it is mute.
Why Part 5 likes this pair
Because the two words rhyme and share three letters, only meaning separates them. If the blank describes an issue that no longer has practical relevance, you need moot. If the blank describes silence or the act of turning off sound, you need mute.
Since the client already signed with a competitor, our proposal is now __.
A word meaning no longer relevant needs moot.
The system will automatically __ the call when the host starts a presentation.
A word meaning turn off the sound needs mute.
Spotting the clue
Decide whether the blank is an irrelevance word or a silence word:
- Does the blank describe something no longer worth debating? → choose moot (a moot point, the question is moot, a moot issue).
- Does the blank describe silence or turning off sound? → choose mute (stayed mute, mute the audio, the mute button).
A quick test: can you replace the blank with irrelevant or academic and keep the meaning, as in an irrelevant question? Then it is moot. Can you replace it with silent or silence, as in stayed silent? Then it is mute. Watch the fixed phrases: moot appears in moot point, the issue is moot, and render it moot, while mute appears in mute button, mute the microphone, and fell mute. Because this pair mixes an abstract adjective with an action verb, it sits alongside the other traps in the sound-alike verb pairs study guide.
Common Part 5 patterns
- Anything about an issue that no longer matters wants moot: a moot point, the debate is moot, render the objection moot, a moot question.
- Anything about silence or turning off sound wants mute: mute the line, stay mute, the mute button, fell mute.
- Grammar cue: describing a settled, irrelevant issue leans moot; an action taken on sound (or the state of being silent) leans mute.
If the blank means no longer worth arguing, choose moot. If it means silent or turn off the sound, choose mute.
Quick recap
- Moot = no longer relevant, already settled by circumstances (adjective) — a moot point changes nothing.
- Mute = silent, or to turn off sound (adjective or verb) — to mute is to silence.
- Part 5 test: swap in irrelevant → moot; swap in silent → mute.
