To utter a sharp shrill cry, usually of short duration; to cry with an acute tone, as an animal; or to make a sharp noise, as a pipe or quill, a wheel, a door and the like. Wheels squeak only when the axle tree is dry. Who can endure to hear one of the rough old Romans, squeaking through the mouth of an eunuch? Zoilus calls the companions of Ulysses, the squeaking pigs of Homer.

To break silence or secrecy for fear or pain; to speak.

A sharp shrill sound suddenly uttered, either of the human voice or of any animal or instrument, such as a child utters in acute pain, or as pigs utter, or as is made by carriage wheels when dry, or by a pipe or reed.
