Etymology
Etymology Information

'definite' originates from Latin, specifically the word 'definitus', where 'de-' meant 'completely' or 'down' and 'finire' meant 'to limit or end'. 'indefinite' originates from Latin, specifically the word 'indefinitus', where the prefix 'in-' meant 'not' plus 'definitus'.

Historical Evolution

'definitus' passed into Old French and Late Latin forms and then into Middle English as 'definite' or similar spellings; 'indefinitus' followed the same route with the negative prefix, producing Middle English 'indefinite' and the modern English forms.

Meaning Changes

Initially, the root meant 'to limit or set bounds'; over time 'definite' came to mean 'clearly defined or certain' while 'indefinite' kept the opposite sense 'not clearly defined or without fixed limits'.
