The frustration of Pengolodh.

Eichiar laim edhellin, ah in•gwaith hain agwistar.

[Elvish languages change, and the people keep changing them further.]

eichia- 'change (intr.)' (cf. Q. _ahya-)
agwista- 'change again (tran.)' (ad + gwista-, cf. Q. vista-)

Speaking about that, what should be a perfective participle of eichia-: is it eichiel? óhiel? óiel?
