means To press or squeeze something soft until it flattens or oozes — or the mushy state of a thing that's been squeezed that way.

from Squish is an echoic word, built to sound like the thing it names — a soft, wet compression. It emerged as a variant alongside 'squash' and 'squeeze,' part of a cluster of sq- words in English that all lean on that same sound to suggest crushing, pressing, or forcing through a tight space. Linguists call this sound symbolism rather than borrowed ancestry — nobody handed English 'squish' from Latin or Old Norse, it just sounded right and stuck.
