attract: [15] Etymologically, attract means literally ‘pull something towards one’. It comes from attract-, the past participial stem of the Latin verb attrahere, a compound formed from the prefix ad- ‘to’ and the verb trahere ‘pull’. It was quite a late formation, of around the mid 15th century, coined on the model of other English verbs, such as abstract and contract, deriving ultimately from Latin trahere.
