Etymology

It is inherited from Proto-Italic *pistlom (“pestle”), inherited from Proto-Indo-European *pis-tlom, from Proto-Indo-European *peys- (“to crush”), the root of pīnsō “to pound”.[1][2][3] The OLD takes the javelin to be probably the same word as the pestle.[4]

Earliest recorded meaning

The OLD's earliest citation is from Plautus, of a mechanical pounder.[4] Köbler's first sources are Cato, for the pestle, and Ennius.[5]

Semantic evolution

It meant a pestle, as in Cato's pīlum fabārium for beans.[3][6] It was also the heavy throwing spear of the Roman legionary, as in Caesar and Cicero, pīlum mūrāle was a pike used by defenders of fortifications.[4][6]

In Medieval Latin it meant a stake, a pile.[7] Latin pīlum gave late Old English pīl “sharp stake”, English pile in the sense of a stake driven into the ground.[8]
