Strong's 4007: περ

περ, an enclitic particle, akin to the preposition περί (Herm. de part. ἄν, p. 6; Curtius, § 359; cf. Lob. Pathol. Elementa, i. 290; others (connect it directly with πέραν, etc., and) give 'throughly' as its fundamental meaning; cf. Bäumlein, Partikeln, p. 198), showing that the idea of the word to which it is annexed must be taken in its fullest extent; it corresponds to the Latincirciter, cunque, German noch so sehr, immerhin, wenigstens, ja; (English however much, very much, altogether, indeed); cf. Hermann ad Vig., p. 791; Klotz ad Devar. ii. 2, p. 722ff; (Donaldson, New Crat. § 178 at the end). In the N. T. it is affixed to the pronoun ὅς and to sundry particles, see διόπερ, ἐάνπερ, εἴπερ, ἐπείπερ, ἐπειδήπερ, ἤπερ, καθάπερ, καίπερ, ὅσπερ, ὥσπερ. ((From Homer down.))
