'Muslim' originates from Arabic, specifically the word 'مسلم' (muslim), where 'سلم' (s-l-m) meant 'to submit' or 'to surrender.'

'مسلم' (muslim) was adopted into English in the 17th century, maintaining its original meaning.

Initially, it meant 'one who submits to God,' and this meaning has largely remained the same in modern usage.
