adhere: [16] Adhere was borrowed, either directly or via French adhérer, from Latin adhaerēre. This in turn was formed from the prefix ad- ‘to’ and the verb haerēre ‘stick’. The past participial stem of haerēre was haes- (the ultimate source of English hesitate), and from adhaes- were formed the Latin originals of adhesion and adhesive.
