Etymology
Etymology Information

'overoptimistic' is a Modern English compound formed from the prefix 'over-' meaning 'excessively' and the adjective 'optimistic'. 'Optimistic' derives ultimately from Latin 'optimus' meaning 'best'.

Historical Evolution

'optimistic' entered English via French/Latin influence (French 'optimiste' / ultimately Latin 'optimus') and formed the adjective 'optimistic'; later, English added the productive prefix 'over-' to create 'overoptimistic' to indicate excess.

Meaning Changes

Initially the Latin root 'optimus' meant 'best'; the sense evolved into 'hopeful about the best outcome' in 'optimistic', and 'overoptimistic' took on the narrower meaning 'excessively hopeful or unrealistically positive'.
