Abate and diminish both mean to become less, but they lean different ways. To abate is for the force of something unpleasant — a storm, pain, an uproar — to die down and lose its intensity. To diminish is for size, quantity, or importance to grow smaller, often gradually and by measurable amounts. Same family — growing less — but abate is an intensity easing off, while diminish is a magnitude shrinking.
abate = the force of something unpleasant dies down (a storm, pain); diminish = a size, number or value shrinks.
Both verbs describe something growing less, which is why they overlap — but each has its own pull, and the roots explain it. Abate comes through Old French abattre, 'to beat down': a violent or overwhelming thing battered until it weakens and subsides. Diminish comes from the Latin minuere, 'to make smaller' (the same root as minor and minute): a reduction in measure. So abate clings to storms, fevers, noise, and anger — forces that flare and then ease — while diminish ranges freely over size, numbers, value, and significance.
abate
To abate is to die down — to become weaker, gentler, or less severe over time. Storms abate, pain abates, public anger abates. The word almost always describes the force of something unpleasant or overwhelming draining away rather than the thing disappearing all at once: it is still there, but its intensity is easing off. Unlike diminish, which tracks a shrinking in size or number, abate is about a violent or unwelcome thing losing its grip. It can also be used transitively — to reduce something deliberately, as in measures taken to abate noise pollution.
diminish
To diminish is to grow smaller, weaker, or fewer — or to make something so. Daylight diminishes through autumn, savings diminish, and pain diminishes with rest. It can also mean to belittle: to diminish someone's achievement is to make it seem smaller than it is. The word shares ground with wane and abate, but diminish is the broadest of the three and works on quantity as readily as on intensity. Its natural opposite is to amplify or to expand — to make greater rather than less.

Picture the two scenes. A rainstorm that tires while a man waits it out under a shelter, until its last drop lands in his outstretched palm — a force easing off — that is abate. A ball bouncing ever lower, each hop two-thirds of the last, fading by smaller and smaller amounts — a magnitude shrinking — that is diminish. Both grow less; abate is an intensity dying down, diminish is an amount getting smaller. If a storm, a pain, or an uproar is easing, it abates; if a size, a number, or a value is shrinking, it diminishes.
abate
- iThe storm finally abated after three days of relentless rain.

diminish
- iDaylight diminishes steadily through the autumn months.
- iiEach extra hour of study brought diminishing returns as fatigue set in.
- iiiNothing he said could diminish the importance of her discovery.
They overlap when an intensity also has a measurable size — pain or demand can abate or diminish, and either sounds right. The tell is what you are watching. If it is the force of something unpleasant easing off (a storm, a fever, an uproar), reach for abate; if it is a size, a number, or an importance shrinking, reach for diminish. Fixed phrases lock it in: 'show no sign of abating' and 'diminishing returns' are not interchangeable.
'Diminish' is the everyday-academic workhorse for shrinking magnitude ('diminishing returns', 'diminish the risk') and fits almost any Writing task. 'Abate' is more formal and idiomatic, reserved for an intensity easing off ('the storm showed no sign of abating', 'the controversy abated') — impressive when used correctly, but never apply it to a plain quantity. Keep the set phrases apart: 'diminishing returns' and 'show no sign of abating' are not interchangeable. Both widen vocabulary range when matched to the right subject.
