-nwasuffix. passive suffix, active participle (intransitive verbs), *[ᴹQ.] perfective participle
-nwa is said to be "a passive suffix" irregularly occurring in the word vanwa "lost" (PE17:63), the word seems to be irregular since the underlying root means "go away" and so vanwa is in a sense a past active participle, *"having gone". Compare PE17:68.

o (2) prep. "with" (MC:216; this is "Qenya"; WJ:367 states that no independent preposition o was used in Quenya. Writers may rather use as.) See ó- below.
