quenya_grammar1-4  Exercise 2: "My ship", "Our ship"
====================================================

  my ship     ciryanya   built by rule: cirya + -nya
  our ship    ciryamma   built by rule: cirya + -mma
              (excluding the person spoken to)

Neither form is attested. The only attested examples in the chapter are
atarinya "my father", ataremma "our father" and mánta "their hand".
Those nouns end in a consonant and take an -i- / -e- before the ending
(-inya, -emma); cirya ends in a vowel, so the -i- is not needed. That
vowel-ending pattern is a guess from the rule, not an attested form.

atarinya is the only safe model because it shows the ending on a real
attested word, but even it comes from a different noun type from cirya.
(The Wikipedia page itself is inconsistent about which noun type takes
-inya and -emma.)
