in the groove

in the groove

English

Etymology

Originally mid-19th century slang with (usually pejorative) reference to the difficulty of leaving a well-worn rut (see in a rut). As back in the groove, the phrase acquired a positive sense of returning to one's usual self after a period of illness, setbacks, &c. With special regard for music, originally 1920s US jazz slang, possibly with reference to the grooves of early records.
