'agglutinatively' originates from the Latin word 'agglutinare,' where 'ad-' meant 'to' and 'glutinare' meant 'to glue.'

'agglutinare' transformed into the French word 'agglutiner,' and eventually became the modern English word 'agglutinate' through Middle English.

Initially, it meant 'to glue or stick together,' but over time it evolved into its current meaning of 'relating to agglutination, especially in linguistics.'
