▪ I. thill1|θɪl|
Also 5 þylle, thyl, 6 thyll. Cf. also fill n.2
[Of uncertain origin: the 14th c. þille, þylle is identical in form with OE. þille, glossed tabulāta, tabulāmen, tabulāmentum, i.e. ‘board, deal, boarding, flooring’, but the sense ‘pole or shaft’ is so different that, without further evidence, it seems unsafe to connect them.
For the OE. þille see theal: none of the cognate words there cited show any approach to the mod. sense of thill.]
a. The pole or shaft by which a wagon, cart, or other vehicle is attached to the animal drawing it, esp. one of the pair of shafts between which a single draught animal is placed. Applied (a) in sing. to the single pole, rarely to the pair of shafts (now only U.S.); (b) in pl. to the pair of shafts.
