around: [14] Around was formed in Middle English from the prefix a- ‘on’ and the noun round (perhaps influenced by the Old French phrase a la reonde ‘in the round, roundabout’). It was slow to usurp existing forms such as about – it does not occur in Shakespeare or the 1611 translation of the Bible – and it does not seem to have become strongly established before the end of the 17th century. The adverb and preposition round may be a shortening of around. => round[around etymology, around origin, 英语词源]
