The verb εἴλλω is in the first place the Attic form of εἰλέω , ἴλλω (*fελ-νέ-ω ) "wind, turn round". But probably as a result of a confusion between such forms (which are close in meaning), and/or because of iotacism, there are also forms conjugated from a present εἴλλω , ἴλλω that correspond to εἰλέω (*fελ-νεω ) "shut in". This confusion (also present in the old manuscripts and some modern lexica) is apparent in the examples given by the Suda. See also iota 310 and iota 322.

[2] Aristophanes, Clouds 761. εἴλλε is the reading of the Suda and most manuscripts of Aristophanes. Against them, modern editors like Coulon prefer ἴλλε (with Cod. M).

[4] Thucydides 2.76.1, abridged (siege of Plataiai, 429 BC); cf. epsilon 1282 and tau 130. The Suda and almost every manuscript of Thucydides have ἐνείλλοντες Only Pi [= Cod. Par. Gr. 1638 (in second hand)] read ἐνίλλοντες accepted by Alberti.
[5] These words (Aristophanes, Clouds 762-3) come immediately after the line already quoted, and somehow have been inserted in the text here. See again at mu 933, the "cockchafer" entry.
