Middle French pile
Ultimate origin
Latin (pila)

Etymology

It is borrowed from Middle French pile (“a heap, a stack”) and directly borrowed from Latin pila (“a pillar; stone barrier, pier”) (see pillar).[2][3][1] The sense development in Latin would have been from a harbour wall of stones to something heaped up.[3]

Earliest recorded meaning

A heap or stack: about 1410 in Barnhart, the early 15th century in Etymonline.[2][3]

Semantic evolution

Middle English pile could also mean a pillar or pier of a bridge (mid-15th century).[3] The verb, to heap up, is from about 1400.[3] A large building, often a pile, may be from the same word, or from a separate Middle English pile, a castle or tower (late 14th century), which the OED treats as of doubtful origin.[3][5] Make one's pile, to make a fortune, is a later use.[1] A nuclear reactor was called an atomic pile in the 20th century.[6][7]

Ultimate origin
Latin (pilum)

Etymology

It is late Old English pīl (“sharp stake; arrow, dart”),[2][3][8] an early borrowing of Latin pilum (“the heavy javelin of the Roman foot soldier”), also the source of German Pfeil (“arrow”).[3][9] The Latin word is of uncertain origin;[3] De Vaan finds its identification with pilum, pestle, defensible.[3]

Earliest recorded meaning

A dart or shaft: before 1000 in the OED;[10] a pointed stake, Old English.[3]

Semantic evolution

A timber or stake driven into the ground is from before 1338, in Mannyng's chronicle.[2] In engineering, a heavy beam driven into the soil to support a structure, the main modern sense, follows.[3][8] The pointed head of a staff or arrow is from the 1590s.[3]

Timeline

  • before 1000 – a dart; a stake.[10][3]
  • before 1338 – a stake driven into the ground.[2]

Ultimate origin
Latin (pilus)

Etymology

It is from Anglo-French pyle or Middle Dutch pijl, both from Latin pilus (“a hair”), a word of uncertain origin.[3][2] Etymonline notes that phonology rules out transmission through Old French peil, poil.[3]

Earliest recorded meaning

Downy plumage: the mid-14th century in Etymonline, about 1350 in Barnhart;[3][2] fine, soft hair, the late 15th century.[3]

Semantic evolution

The soft, raised surface of a fabric such as velvet or a carpet is from the 1560s.[3]

Timeline

  • c. 1350 – plumage.[2][3]
  • late 15th century – soft hair.[3]
  • 1560s – the nap of cloth.[3]

Modern meaning
