dactyl

Etymology

It is inherited from Middle English dactil, also dactile,^[2][3][4] borrowed from Latin dactylus,^{[5][6][7][4][3]} perhaps through French dactyle,^[5] from Ancient Greek δάκτυλος (dáktulos, “finger, toe”).^[5][6][4][3] The Greek word also meant a finger's breadth as a unit of measure, and a date,^[6][5] and it is of unknown or uncertain origin.^[6][7][8] The metrical foot was named after the three joints of a finger.^[7][6][8][9] Barnhart counts date, the fruit, as a doublet of the word,^[7] while Klein separates the Greek word for the date from the one for the finger, and denies that the latter is cognate with Latin digitus (“finger”).^[8]

Earliest recorded meaning

A metrical foot: before 1382, in the prologue to Job in the Wycliffite Bible, "Vers of sixe feet, rennende with dactile and sponde feet".^[2][7] The OED dates its quotation from the same prologue c. 1420.^[5]

Semantic evolution

In Middle English the word also named the fruit of the date palm: Trevisa's translation of Bartholomaeus, from before 1398, speaks of the sweetness of "dactyles", and says the fruit "hath þat name for likenesse of fyngres".^[2] That use is recorded until 1656.^[5] The metrical term moved with the verse it described: a long syllable and two short ones in classical verse, a stressed syllable and two unstressed ones in English verse.^[5][6][10] Later uses went back to the Greek literal sense, as a term of natural history: a mollusc, the piddock, from 1803, and a finger or toe from 1889, a sense Merriam-Webster Unabridged treats as a New Latin borrowing from the Greek.^[5][3]
