ὥσπερ γε καὶ λίθων καὶ ξύλων ἃν δέῃ συναρμοσθῆναι, ἔστι, κἂν ὁπωσοῦν καταβεβλημένα τύχῃ, συναρμόσαι αὐτὰ εὐπετῶς, ἢν ἔχῃ γνωρίσματα ὥστ᾽ εὔδηλον εἶναι ἐξ ὁποίας ἕκαστον χώρας αὐτῶν ἐστιν.
Yes, λίθων καὶ ξύλων are partitive genitives depending on ἃ.
Sorry, there is no ἄ in my text. This Gen partitivus seems to be used as subject. And one more question here: κἄν means even if, and there is no verb that follows, right?
ἃν = ἃ ἂν
ok, i did not know that they could combine so, but even without ἄ, can it still be ok?
ἃν is ἃ ἂν in crasis (adjacent vowels routinely coalesce), so that’s an indefinite relative clause (ἃν δέῃ συναρμοσθῆναι “that have to be fitted together”) introduced by the partitive genitive.
Then ἔστι … συναρμόσαι αὐτὰ εὐπετῶς is the main clause (“it’s possible … to fit them together without trouble”). κἂν (= καὶ ἐὰν) ὁπωσοῦν καταβεβλημένα τύχῃ “even if they happen to have been thrown down any old how”—τύχῃ is the verb. Then the condition to the main clause, ἢν ἔχῃ etc.
yes, it is clear now, thankx
