What does diminish mean?
Diminish is a formal verb meaning to make or become smaller, weaker, or less significant. It can describe concrete reduction, as when supplies diminish over time, or abstract loss, as when criticism fails to diminish someone's reputation. Used transitively, it takes an object ('the crisis diminished public confidence'); used intransitively, it describes gradual decline ('his hearing has diminished with age'). A third sense, somewhat more pointed, means to belittle — to treat a person's efforts or accomplishments as unimportant, as in 'she refused to let rivals diminish her work.' The most famous fixed phrase is 'diminishing returns,' an economic term for the point at which additional investment yields progressively smaller benefits. The word derives ultimately from the Latin minuere, 'to lessen,' the same root behind 'miniature' and 'minute.' Its tone is measured and slightly elevated, making it a natural choice for careful writing where plainer words like 'cut' or 'shrink' would sound too blunt.

Every time you say 'diminish,' you're echoing the same ancient Latin root that gave us 'miniature,' 'minute,' and 'minus' — all about making things small.

Etymology of diminish
Diminish entered English in the late Middle Ages (around the early 15th century), borrowed from a blend of Old French diminuer and its Latin source diminuere, itself formed from minuere, 'to lessen.' The root min- connotes smallness and also underlies related English words such as 'miniature,' 'minute,' 'minor,' 'minimum,' and 'minus.' The noun form 'diminution' came into English around the same period.
