Ike

Ike is an English short form of Isaac, the Hebrew name associated with laughter. The biblical Isaac gives it a much older background than its brief sound might suggest. As with many familiar forms, Ike can be used either as a nickname or as a complete given name in its own right.

A separate famous use belonged to Dwight D. Eisenhower, whose nickname Ike came from his surname rather than from Isaac. That distinction helps explain why a well-known bearer does not always reveal a name's usual derivation. Families choosing Ike through Isaac can retain the laughter meaning, while those honoring Eisenhower or another particular Ike may be following a different personal connection.
