• pile from Old English:

  Three different Latin words lie behind three different types of pile. Pile meaning ‘heap’ comes via Old French, from Latin pila ‘pillar, pier’. The association with money in make one's pile is from the phrase ‘pile of wealth’ (Shakespeare Henry VIII: What piles of wealth hath he accumulated To his own portion?). Pile meaning a ‘heavy post’ driven into the ground to support a superstructure was pīl ‘dart, arrow’, and ‘pointed stake’ in Old English. It was adopted early into Germanic languages from Latin pilum ‘(heavy) javelin’. The pile of a carpet was first recorded in the sense ‘downy feather’. It comes from Latin pilus ‘hair’, found also in depilatory (early 17th century). The current sense of pile dates from the mid 16th century.
