¹ For apparent repetitions of the same element where really the element has become differentiated in one of its uses, cp. λλ in the same sentence as ῔λλοι, and igitur in the same sentence as agitur, &c.: on the other hand, there are many repetitions where one element may really reinforce and repeat the other—thus cp. possibly the Homeric μν κεν, as opposed to be δ κεν or δ῔ν, &c. The two classes cannot be always distinguished, e.g. in a use like εἴ περ γρ τε…κα…λλ τε κα (Il. 1, 81) it is dangerous to decide absolutely how far each τε and κα still retains its early force.

² There is no need to call this use always Jussive or Optative in origin : both Moods (Subj. and Opt.) as well as the Fut. Ind. are capable of a neutral use which may be called Concessive. On the other hand there is no need to altogether exclude the ‘Hortative’ and ‘Wishing’ use as origins.
