What does baa mean?
Baa is the conventional English rendering of the sound made by a sheep. It functions both as a noun, referring to the cry itself, and as a verb meaning to utter that cry. The word is onomatopoeic: it arose not from another language but from an attempt to capture an animal noise in human speech, first recorded in English around the early seventeenth century. Because it is inherently informal, it appears most often in children's books, nursery rhymes, jokes, and descriptions of farm life rather than in formal writing. Related terms such as bleat cover similar territory, though bleat is broader, applying also to goats. Cultures render the same ovine sound differently — in some languages the equivalent word sounds strikingly unlike 'baa' — which makes the word a small reminder that even our simplest vocabulary is shaped by perception as much as by nature. Simple as it seems, baa occupies a fixed place in English as the canonical voice of the sheep.
The cry of a sheep.
"The baas of the flock echoed down the valley."
Almost always used informally or humorously.
To make the characteristic crying sound of a sheep.
"The ewes baaed impatiently at feeding time."
The plural simply adds -s to the singular noun form.
"We counted a dozen distinct baas coming from the pen."
'Baa' is one of the rare English words that exists purely because someone listened closely enough to a sheep to write down what it sounded like.

Etymology of baa
Baa is an onomatopoeic formation, created within English by imitation of the sound a sheep makes rather than borrowed from another language. It was first recorded in writing in the early seventeenth century. As a purely imitative word, it has no classical root and no true cognates from Latin or Greek, though other languages have independently coined their own versions of the sheep's cry.
