Appleyard's Quenya is a conlang made by Anthony Appleyard on the basis of J. R. R. Tolkien's Quenya. It contains so many inventions of Appleyard's that it is best regarded as a derivative work and a conlang in itself rather than a reconstruction of Tolkien's Quenya.
Especially spurious are the following logical conjunctions entirely unattested in the Quenya corpus:
A-ki if A exists/is there X iki Y X if Y; Y implies X A-ke caused by A X ike Y X because Y A-kei intentionally caused by A X ikei Y in order that X, Y A-ka if and only if A exists e X ika Y X if and only if Y; X eqv Y if and only if A is there A-ko causing A X iko Y X therefore Y A-koi intentionally causing A X ikoi Y X in order that Y A-ku implying that A exists X iku Y if X then Y; X implies Y implying that A is there Plural: add `-n', e.g. `kiryakan' = "if and only if (there are) ships".
