around:  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
c. 1300, "in circumference," from phrase on round. Rare before 1600. In sense of "here and there with no fixed direction" it is 1776, American English (properly about). Of time, from 1888. To have been around "gained worldly experience" is from 1927, U.S. colloquial.
