volley: [16] A volley is etymologically a ‘flight’ of something, such as missiles. The word comes via Old French volee from Vulgar Latin *volāta ‘flight’, which was a noun use of the feminine past participle of Latin volāre ‘fly’ (source also of English volatile [17]). The origins of this are not certain, although it may be distantly related to Sanskrit garutmant- ‘bird’. The use of volley as a sporting term for a ‘shot hit before the ball bounces’ dates from the 19th century. => volatile[volley etymology, volley origin, 英语词源]
