Etymology
Etymology Information

'strengthen' originates from English, specifically formed from the noun 'strength' plus the verb-forming suffix '-en', where 'strength' derived from Old English 'strengðu' (from 'strang'/'strang-') and '-en' meant 'to make' or 'to become'.

Historical Evolution

'strengthen' changed from Middle English forms such as 'strenchen'/'strengthen' and eventually became the modern English word 'strengthen' by regularization of spelling and pronunciation.

Meaning Changes

Initially, it meant 'to make strong' or 'to become strong', and over time it has retained that basic meaning while extending to figurative senses like 'to increase influence or effectiveness'.
