expandvsshrink
Expand means to grow larger — in size, number, or scope. Shrink means the opposite: to get smaller, to contract or pull in. One pushes the edges outward; the other draws them back toward the centre.
From one still point in the middle, square frames push outward, each bigger than the last, until they ride all the way to the edges.
/ɪkˈspænd//ɪkˈspænd/·verbA wool sweater, fresh from a hot wash, draws in from every side — sleeves and body pulling tight, well inside the size it started at.
/ʃrɪŋk//ʃrɪŋk/·verbBoth words are about a thing changing size, and they pull in opposite directions. Expand pushes the boundary outward — more space, more volume, more detail; shrink draws it back in toward the middle. The roots match the motion: expand is from the Latin expandere, 'to spread out', while shrink is an old Germanic word for wrinkling and drawing together. If a thing is getting bigger it expands; if it is getting smaller it shrinks.
What each means
expand
To expand is to spread out — to grow larger in size, number, or reach. Heated gas expands, a company expands into new markets, and a writer is asked to expand on a point by adding detail. The Latin expandere means 'to spread out', and the word keeps that outward motion: the edges move away while the centre stays put. It is the natural opposite of shrink and contract. In its 'expand on' form the sense shifts slightly, from growing bigger to explaining more fully.
shrink
To shrink is to grow smaller — to contract in size, amount, or extent. Wool shrinks in hot water; a glacier shrinks as it melts; a market shrinks when buyers vanish. The word carries a second, bodily sense too: to shrink back is to flinch and recoil, pulling inward away from something feared. Both meanings share one motion — a drawing-in, a retreat from the space once filled. What shrinks does not merely lessen; it withdraws, leaving the outline of what it used to be.

How to remember the difference
Watch the edges. Expand and the edges race outward — a balloon filling, a city spreading, an answer growing more detailed when you 'expand on' it. Shrink and the edges pull back in — a jumper after a hot wash, a drying puddle, someone who 'shrinks from' a fight stepping away. Same object, one question: are its edges moving out, or in? Out is expand; in is shrink.
Examples
expand
- The company plans to expand into three new countries next year.
- Heat the metal bar and it will expand by a few millimetres.
- Could you expand on that last point? I'm not sure I followed it.
shrink
- The sweater shrank two sizes the first time I washed it.

They are opposites for size, but each has a second, figurative life: 'expand on' an idea means add detail, while 'shrink from' something means flinch away from it. Only the size senses are true antonyms — don't swap the figurative ones.
