Kip

Kip is used as an independent name and as a nickname, sometimes for Christopher. When that longer name is intended, the connection leads to Greek elements meaning “Christ-bearer.” Kip by itself does not have to carry that meaning, because not every bearer has Christopher as a full name.

Physicist and Nobel laureate Kip Thorne is a notable example whose first name is Kip rather than an abbreviation of Christopher. Kipp is a spelling alternative. The name also has an everyday British English association with sleep, which is separate from the personal-name history. Its compact form can therefore be complete on a birth certificate, while a family's intended longer-name connection remains a matter of individual usage.
