The twenty most useful
If you take twenty words from this page, take these — the ones that do work no other word on the list quite does.
- magnanimous — generosity aimed at someone who did not earn it
- measured — the most useful praise word for a difficult conversation
- mercurial — mood change as a settled trait, not an episode
- meticulous — care at the level of detail, not of effort
- mundane — dullness without cruelty
- moribund — for institutions rather than people
- mawkish — sentimentality that has gone off
- manifest — obvious, in a register above obvious
- malleable — flattering or damning depending on the noun
- methodical — order as a habit rather than a result
- meagre — scarcity with a note of grievance
- magisterial — authority that does not raise its voice
- murky — physical and moral in one word
- momentous — weight without volume
- mordant — wit with acid in it
- mellow — the rare M-word with no edge at all
- misguided — criticism that grants good intentions
- motionless — stronger than still, because it implies effort
- mercenary — motive named without naming a person
- melancholy — sadness that has been thought about
The positive ones
Praise-side words. Some writers reserve masterful for command over people and masterly for skill, but dictionaries record both senses for masterful and the older one is the command sense. Worth knowing as a preference, not a rule.
magnanimous, magnetic, magnificent, majestic, marvellous, masterly, matchless, mature, measured, meaningful, memorable, meritorious, merciful, mesmerising, methodical, meticulous, mighty, mindful, mirthful, modest, moving, mutual
The negative ones
Criticism-side words. Mediocre is the cruellest word here precisely because it makes no accusation.
maladroit, malevolent, malicious, manipulative, mawkish, meagre, mean, measly, meddlesome, mediocre, mercenary, merciless, messy, miserly, misguided, monotonous, morbid, mundane, murky
Describing appearance
M is thin on appearance words and strong on texture — mottled and misshapen do more work than any colour the letter offers. Its best descriptive words are smells rather than sights: musty and musky are listed above but belong to the nose, not the eye.
magenta, matt, milky, miniature, misshapen, misty, mottled, muddy, muscular
Common mistakes
| Pair | The difference that matters |
|---|---|
| masterly / masterful | A traditional distinction gives masterly the skill and masterful the command, but Merriam-Webster records both senses for masterful and calls the split an imposed rule rather than an error. Use it if you like the precision; do not correct anyone with it. |
| meagre / measly | Both mean too little. Meagre is neutral about blame; measly accuses somebody of meanness. |
| mendacious / malicious | Mendacious means lying. Malicious means intending harm. A lie can be told without malice. |
| moral / moralistic | Moral concerns right and wrong. Moralistic means preachy about it. |
| mystical / mythical | Mystical is about spiritual mystery. Mythical means it does not exist. |
