Proliferate means to increase rapidly in number, multiplying at a pace that feeds on itself. Diminish means the opposite: to make or become smaller, weaker, or fewer. One multiplies until it's everywhere; the other dwindles toward less.
Both verbs change how much of something there is, and they run in opposite directions. Proliferate comes from the Latin proles, 'offspring' — to proliferate is literally to keep bearing offspring, so each new instance is also a new source, and growth compounds. Diminish comes from minuere, 'to make smaller', and works the other way, shrinking quantity or intensity by degrees. One word is multiplication that reads as nothing until it's suddenly everything; the other is a steady fade toward less.
proliferate
To proliferate is to multiply at a pace that feeds on itself: cells proliferate, weeds proliferate, and so do startups, streaming services, and conspiracy theories. The word descends from the Latin proles, 'offspring' — to proliferate is literally to keep bearing offspring, which is why it means compounding growth rather than mere increase. Each new instance is also a new source. What began as one is, suddenly, everywhere — and the speed itself is the story.
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.

Watch the count. Proliferate is the single cell splitting into two, then four, the rounds coming faster because every new cell can make more — it reads as nothing in the corner until, between two glances, the whole field is a wall of them. Diminish is the bouncing ball whose rebounds shrink by two-thirds each time, trading big losses for ever-smaller ones until it quivers above the floor. One multiplies until it's everywhere; the other dwindles toward less. If the numbers explode by compounding, it proliferates; if they shrink away, they diminish.

They contrast as compounding growth against gradual decline — diminish's neighbours sit among proliferate's opposites. Proliferate stresses self-feeding speed (each instance a new source), where diminish is a steady fade; diminish also has a belittling sense ('to diminish an achievement') that proliferate has no parallel to.
