Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

ĭōta, n. indec., = ἰῶτα, the name of the Greek ι, iota (in Gr. trisyl., in Lat. dissyl.): ut iota litteram tollas, Cic. de Or. 3, 12, 43: unum de titulo tollere iota, Mart. 2, 93, 4.
Sometimes (on account of littera) ĭōta, ae, f., Aus. Idyll. in Monosyllab. de Litteris, (12), 23: littera iotae similis, id. ib. 7.
