The sign for "goat" uses a bent-V handshape. Touch your chin, then touch your upper forehead.
The handshape starts and stays in a "bent-V" shape. The movement is
quick.
Memory aid: Think of a goat's beard and horns.
GOAT:



Notes:
Sure, at one time this sign probably used the sign OLD and then the
sign "two horns pointing backward over the head." But the fact is,
signs evolve and tend to become more simple, with fewer handshapes.
Thus regardless of how this sign "was" done in the past, it is
currently generally done (by adult native Deaf signers) using only
"one" handshape.
