Doreen (UK: /ˈdɔːriːn/ DOR-een, US: /dɔːˈriːn/ dor-EEN), also occasionally spelt Dorean or Dorine, is a feminine given name, usually found in English-speaking countries.
It is a combination of Dora with the suffix -een,[1] which is related to the -ín suffix used in Irish, usually signifying small size or as an endearment.
[2][3] Dora is a variant of Dorothy / Dorothea, which derives from the Late Greek name Δωρόθεος (Dorotheos), which meant "gift of god" (from δῶρον/doron meaning "gift" and θεός/theos meaning "god".
[4] It is thus related to many other feminine given names, including Dorian, Dorinda,[1] Theodora and Isidora.
[4] Diminutive forms include Dee, Dodie, Dolly, Dory, Dot, Dottie, and Dotty.
