Same entry in other lexica. The headword -- masculine nominative singular of the future participle (middle, as always) of e)ntugxa/nw -- must be quoted from somewhere. (Extant possibilities are all post-classical.)
This verb has many meanings, but a specific one in philosophy, 'meet others or another in a session (arranged or not) of dialectic discussion in the baths' (see e)/nteucis, epsilon 1468). It may also mean 'meet (by rendezvous or not) with an official to make a petition'. See LSJ at web address 1.
The future passive participle which constitutes the gloss belongs to the verb diale/gomai, regarded as a deponent verb with alternative middle or passive forms. It apparently invokes the process of being questioned, examined and refuted (e)/legcis) that characterizes dialectic.
The headword verb represents well the continuing presence of the image of 'aiming and hitting with a little bit of luck' in tugxa/nw and its compounds (alpha 3591, sigma 1639 and cross-references). When I make a rendezvous with, or otherwise try to meet, someone, it is not clear that he will be there; when I attend a discussion, a committee meeting or seminar, it is never certain exactly who will be there; when I run into someone by chance in the street or the baths and stay to talk, it may be by chance but with a sense of welcome opportunity. It is as if I had hit a target. See A.W. Gomme's useful note on the meaning of e)/tuxe in his Historical Commentary on Thucydides, vol. 3, pp. 488-89.
