'indicatively' originates from Latin, specifically the word 'indicativus,' where 'indic-' meant 'to point out' and '-ativus' was a suffix forming adjectives.

'indicativus' transformed into the Old French word 'indicatif,' and eventually became the modern English word 'indicative' through Middle English.

Initially, it meant 'to point out or indicate,' and this meaning has largely remained the same in modern usage.
