Chinstrap → It is formed from "chin" (from Old English "cyn", meaning the lower part of the face) and "strap" (from Old English "streap", meaning a strip of material). The word "chinstrap" refers to a strap that goes under the chin, typically used to secure something in place.
Think of the 'chin' as the part of your face where the strap goes under, and 'strap' as the material that holds something in place. This helps you remember that a chinstrap is a strap that secures under the chin.
