What does purr mean?
To purr is to make a low, continuous, vibrating sound, most famously the sound of a contented cat. The verb is also used figuratively for a person expressing pleasure, as in “She purred with delight,” and for machines or vehicles producing a similar rumbling noise, such as a well-running engine. As a noun, a purr is the sound itself, as in “The cat’s purr filled the quiet room.” Purr is especially associated with feline companionship and domestic comfort, and writers use it to create a warm, intimate, or playful atmosphere. Although purring is often linked with happiness, cats can also purr when they are anxious, frightened, in pain, or seeking food or attention, so the sound should not always be treated as proof that a cat is relaxed.

Where does purr come from?
The word purr is of uncertain origin. It appears in English in the early 19th century, probably as an imitative word formed to represent the low rumbling sound made by a cat. The verb developed both a literal sense for making that sound and figurative senses for expressing contentment or producing a similar mechanical noise.
