twin sister
Identical female counterpart
A twin sister is a female sibling born from the same pregnancy.
The term specifies both the twin relationship and the sibling's sex: My twin sister and I look nothing alike.
Twin sisters may be identical (from one fertilized egg) or fraternal (from two).
The phrase often implies a close bond beyond ordinary siblinghood.
