What does growl mean?
Growl describes a low, deep, threatening sound and the act of making it. The word is especially associated with animals, as in a dog growling at a stranger, but people also growl when they speak angrily, warn someone, or express displeasure in a low, forceful way. A growl can function as a noun, meaning either the sound itself or a stern, hostile expression, and it may also describe a deep mechanical rumble. Its force often comes from combining a restrained volume with an implied threat, making it more unsettling than an ordinary shout. Although “growl” may imply a tone rather than literal speech, the term is also used for harsh, roughly articulated remarks. The word is familiar in both British and American English and appears in figurative expressions involving thunder, engines, stomachs, and threatening people. Its long history and recognizable sound make it especially effective for conveying warning, anger, and controlled aggression.
To make a low, deep, threatening sound, or to speak in a harsh, menacing manner.
