Tib

English diminutive of Theobald, German
"courageous people"

Tib Origin and Meaning

The name Tib is a boy's name meaning "courageous people".

Tib was a unisex nickname in the 13th century, used as a short form of Theobald and Isabel. As Theobald waned in popularity, it became far more associated with girls, so much so that Tib was a term for young girls by the 16th century.

Now, of course, no such association exists, and Tib could be used on either sex.
