threshing floor a surface of hard ground or stone where grain was threshed out, either by beating or having animals trample upon it The meaning of ἅλων as ‘threshing floor’ forms the basis for the figurative extension of meaning (a metonymy) referring to the threshed grain still lying on the threshing floor (see 3.43). The meaning may be made clear by rendering ‘to thresh out completely all of the grain.’ On the other hand, it is possible to interpret ἅλων in MAT 3:12 in a literal sense and translate ‘he will clean up his threshing floor,’ that is, by gathering up the grain and getting rid of the straw and chaff.

Thayer's Greek Lexicon
ἅλων, -wvos, 7, (in Sept. also 6, cf. Ruth iii. 2; Job Xxxix. 12), i. q. ἡ ἅλως, gen. ἅλω, a ground-plot or threshing-floor, i. 6. a place in the field itself, made hard after the harvest by a roller, where the grain was threshed out: Mt. iii. 12; Lk. iii. 17. In both these pass., by meton. of the container for the thing contained, ἅλων is the heap of grain, the flooring, already indeed threshed out, but still mixed with chaff and straw, like Hebr. 173, Ruth iii. 2; Job xxxix. 12 (Sept. in each place adGva) ; [al. adhere to the primary meaning. Used by Aristot. de vent. 3, Opp. ii. 913", 14].

Moulton & Milligan — Vocabulary of the Greek NT
ἅλων. The old form ἅλως, in the ‘ Attic” declension, is still very much more common in papyri, e.g. P Fay 11218 (a.p. 99) μὴ σπουδασέτωσαν ἅλω, ‘do not let them be in a hurry with the threshing-floor,” P Lond 31417 (a.p. 149) (=II. Ῥ- 190) ἐφ᾽ ἅλῳ τῶν ἐδαφῶν, 7. 6. as soon as the corn is threshed; but the NT third declension form is found in P Tebt I. 848 (8.6. 118) ἁλώνωι (= wv, see Proleg. p. 49), PSI 371 (A.D. 82) ἐφ᾽ ἁλώνων, BGU 11. 651° (ii/a.p.), 2. IIT. 7591 (ii/a.p.), P Strass 1. 10° (jii/a-p.), P Lond 1239% (a.p. 278-81) (= III. p. 52), and 7. 9767 (A.D. 315) (=TII. p. 231). See further Crénert Jem. Herc., p- ix. The derivative ἡ GAwvia, the space reserved for a threshingfloor, occurs P Tebt II. 3465 (early i/a.b.), BGU I. 146% (ii/iii a.p.), P Lond, 1170 verso**4 (A.D. 258-9) (= III. p. 202), and P Oxy X. 12558 (A.D. 292).
