Made stronger or more powerful in body, mind, or structure.
From Old English 'strengu' meaning strength, combined with the suffix '-en' to make a verb, and '-ed' for past tense. The word evolved to mean making something more robust or resilient over time.
Strengthened is everywhere in fitness culture, but it originally described fortifying castles and city walls—your ancestors used this word to talk about making stone barriers stronger against attack!
