[1] The headword is perfect middle/passive participle, masculine nominative singular, of parako/ptw. See already at kappa 1981 (end), though the present instance is glossed (here and in other lexica; references at Photius pi241 Theodoridis) as personal.
[2] A version of Aristophanes, Acharnians 512, where the best ms has diakekomme/na. The comment which now follows comes from the scholia to line 517, which really does have parakekomme/na: see below, at n. 5.
[3] The scholia have the order reversed here: "they are accustomed to call misgravers 'misstrikers'", which makes better sense as commentary on the word in question. "Misstrikers" is a translation of the active participle of patako/ptw.
[4] A phrase said by the scholia to be used "amongst Athenians", but more specifically found in Demosthenes 18.242, whence Harpokration s.v., Synagoge, Photius pi295 Theodoridis, and pi 431.
[5] Aristophanes, Acharnians 517-518.
