Resembling or having qualities similar to a guitar in shape, sound, or function.
From 'guitar' + '-like' (resembling or similar to). The suffix '-like' comes from Old English 'lic' meaning 'body' or 'form,' and came to mean 'similar to.' This is a standard English word formation.
Linguists call '-like' one of the most productive suffixes in English because you can add it to basically any noun to create a new adjective, so 'guitarlike' works instantly even if you've never heard it before — try 'pizzalike' or 'mouselike' and English speakers understand immediately.
