The word "baa-lamb" typically refers to a young sheep that makes a "baa" sound. However, there are a number of synonyms that can be used to describe a lamb depending on its age and gender. A "ewe lamb" is a young female sheep, while a "ram lamb" is a young male sheep. If the lamb is less than one year old, it can also be referred to as a "spring lamb" or a "sucker lamb." Other less common synonyms include "tup lamb," which refers to a male lamb intended for breeding purposes, and "shorn lamb," which refers to a lamb that has had its wool shorn off.
