Betje

Betje is a Dutch diminutive form of Elisabeth, which traces back through Latin and Greek to the Hebrew name Elisheba, meaning something along the lines of my God is an oath or my God is abundance. It has long been a familiar, affectionate form used in the Netherlands, carrying the warmth typical of Dutch pet-name suffixes such as -je. The name is closely related to Bette, Lies, Liesje, and the wider international family of Elisabeth variants including Elizabeth and Isabella.
