frenulum
|fren-u-lum|
/ˈfrɛn.jʊ.ləm/
small restraining fold
Etymology
'frenulum' originates from Latin, specifically the word 'frenulum', a diminutive of 'frenum' where 'frenum' meant 'bridle' or 'rein'.
'frenulum' was used in Late and Medieval Latin for a small bridle or restraining band and was adopted into New Latin anatomical terminology; it entered modern English via scientific/medical Latin usage as 'frenulum'.
Initially it meant 'a small bridle or rein,' but over time it evolved into its anatomical sense of 'a small fold of tissue that restrains movement.'
