IPA: //ˈseɪfˌkiːpɪŋ//
KK: /ˈseɪfˌkiːpɪŋ/
The action of keeping something safe or the condition of being protected from harm or danger.
The museum has special rooms for the safekeeping of valuable artifacts.
Safekeeping is formed from "safe" (from Old French *sauf*, meaning unharmed or protected) and "keeping" (from Old English *cepan*, meaning to hold or to keep). The word refers to the act of keeping something in a state of safety or protection.
Think of keeping something 'protected' ('safe') and 'holding' it ('keeping') — that's what safekeeping means.
