Late Middle English (in the senses 'enfold' and 'entangle'; formerly also as envolve): from Latin involvere, from in- 'into' + volvere 'to roll'.

• revolve from Late Middle English:

  The Latin verb volvere had the sense ‘to turn round, roll, tumble’; add re- in front and you get meaning such as ‘turn back, turn round’. This is the basic idea behind revolve and its offshoots: revolution (Late Middle English) which only came to mean the overthrow of a government in 1600, and which developed the form rev for the turning over of a motor in the early 20th century; and revolt (mid 16th century) initially used politically, and developing the sense ‘to make someone turn away in disgust’ in the mid 18th century. The sense ‘roll, tumble’ of volvere developed into vault, both for the sense ‘leap’ (mid 16th century) which came via Old French volter ‘to turn (a horse), gambol’, and for the arch that springs up to form a roof (Middle English). The turning sense is found in voluble (Middle English) initially used to mean ‘turning’, but was used for words rolling out of the mouth by the late 16th century, and in volume (Late Middle English) originally a rolled scroll rather than a book, but with the sense ‘quantity’ coming from an obsolete meaning ‘size or extent (of a book)’ by the early 16th century. Convoluted (late 18th century) comes from convolvere ‘rolled together, intertwined’ (the plant convolvulus, from the same root, that climbs by turning its stem around a support already existed as a word in Latin, where it could also mean a caterpillar that rolls itself up in a leaf); while devolve (Late Middle English) comes from its opposite devolvere ‘to unroll, roll down’; and involve (Late Middle English) from involvere ‘to roll in’.
