I suppose (hupolambanō). Old verb, originally to take up from under, to bear away as on high, to take up in speech (Luk 10:30), to take up in mind or to assume as here and Act 2:15. Here with an air of supercilious indifference (Plummer).
The most (to pleion). The more.
Rightly (orthōs). Correctly. Socrates was fond of panu orthōs. The end of the argument.
