Betty

Betty is a diminutive or pet form of the name Elizabeth, which is derived from the Hebrew name Elisheva.

The name Elisheva is composed of the Hebrew elements 'el' meaning 'God' and 'shava' meaning 'oath' or 'promise', so the name Elizabeth can be interpreted as meaning 'God is my oath' or 'consecrated to God'.

The name Betty emerged as a nickname for Elizabeth in the Middle Ages and became popular as a given name in its own right in the 19th and 20th centuries.

While Betty is a diminutive, it has a charming and timeless quality, and is often associated with a sense of warmth and nostalgia.
