means The act of forcibly pushing unwanted thoughts, feelings, or memories out of conscious awareness, often without realizing you're doing it.

from From Latin 'reprimere,' to press back or hold down — built from 're-' (back) plus 'premere' (to press), the same root that gives us 'press' and 'pressure.' The literal sense of physically pushing something down arrived in English in the 1400s; Freud later borrowed the word for the mind's habit of pressing inconvenient feelings beneath the surface, where they tend to push back.
