Etymology
the word 'groove' originated in middle english as 'grofe' or 'groof', meaning a mine shaft or pit, likely derived from the old english 'grāf', meaning a trench or ditch, which is related to 'grafan', meaning 'to dig'. this origin in excavation and digging provides the literal foundation for its primary meaning of a long, narrow cut. the musical sense, emerging in the 1930s, is a metaphorical extension from the idea of a phonograph record's spiral groove guiding the needle, which then evolved to describe the pleasurable, steady rhythm one follows. the verb sense of performing effortlessly follows logically from being 'in' that steady, guiding pattern.
Analysis
the word 'groove' is a simplex word of english origin. it does not break down into smaller, meaningful morphemes within modern english spelling.
