purr
PURR
/pɜːr/
To make a low, continuous, vibrating sound, expressing contentment or pleasure, typical of a cat.
While primarily associated with cats, purr can also describe the smooth, low hum of a well-tuned engine or a person speaking in a low, pleased, or seductive voice.
The story behind the word. The word purr is onomatopoeic, meaning it was created to mimic the actual sound it describes. It first appeared in written English in the late 16th century, replacing older, less specific words like 'murr' or 'mew'.
