twins
Born together, identical
Twins are two offspring born from the same pregnancy.
Identical twins develop from a single fertilized egg and share the same genetic makeup; fraternal twins develop from separate eggs and are no more genetically similar than other siblings.
The word extends to any closely matched pair: twin cities, twin beds.
As a verb, to twin is to pair or match: The program twins students with mentors. (Capitalized Twins refers to the zodiac sign or sports teams.)
