Module:Gaillean

From Yezur Wiki

This is the documentation for Module:Gaillean, the noun-declension module for Gaillean (YAQ-GA) on the Yezur wiki. It is not called directly: Template:YAQ-GA-decl is a bare {{#invoke:Gaillean|decl}} and the module reads the template's own parameters from the parent frame, so a Dictionary entry writes {{YAQ-GA-decl|class=F}} under its declension heading. The module returns a wikitable of five cases — nominative, genitive, dative, accusative and vocative — in columns headed SG and PL.

Forms are built by concatenation from the citation form. The module does not call Module:Auphen; the Gaillean sound data at Module:Auphen/YAQ-GA serves the entry's pronunciation line instead.

Parameters

Parameter Purpose
word (or 1) The citation form to decline. Defaults to the page name when omitted, which is how entries use it.
class (or 2) The noun class, in the letters recorded on the entry's {{head}} line. Required; an unrecognised value returns an error message in place of the table.
stem The stem of an irregular noun, the form in -r its other forms are built on. Read only for classes MX, FX and NX, where it takes precedence over the module's own table of stems.
nopl Any non-empty value suppresses the plural, whose cells are then filled with a dash. For nouns with a unique referent.

Regular classes

The classes below decline by rule, each tied to the ending of the citation form. The module removes that ending and adds the endings given here; a lemma that does not carry its class's ending returns an error rather than a table. Singular and plural are given in that order.

Class Lemma in NOM GEN DAT ACC VOC
F -a -a / -ar -an / -aori -ae / -uz -as / -ax -a / -a
M1 -e -e / -o -in / -ori -i / -uz -ez / -orz bare stem / -or
M2 -at -at / -o -ant / -ori -i / -on -ats / -ae -a / -o
N1 -uz -uz / -ia -uzn / -iari -i / -ibhi -uz / -ia -u / -i
N2 -u -u / -ur -un / -uri -i / -uri -u / -ur -u / -ur
NP -o -o -on -i -o -o

Class NP is a one-off: it follows N2 with -o wherever that class has -u, and has no plural at all, the plural cells being dashed without nopl. It is carried at present only by Thaemo.

Irregular classes

Classes MX, FX and NX do not decline from the citation form, and differ from one another only in the gender they record: the module declines all three alike. They decline from a stem in -r, taken from stem or, failing that, from the module's own table of 44 stems keyed by lemma; where neither supplies one the module returns an error. No entry passes stem at present, so every irregular relies on the table. Several of its stems belong to transparent compounds and repeat the stem of the head noun, so velna-aevr takes velna-aetover beside aevr → aetover.

The nominative singular is the citation form itself and the nominative plural the bare stem. The other singulars are built on a shortened stem — the stem less its final -r and the vowel before it — and take -un, -i, -as and -i for genitive, dative, accusative and vocative. The genitive, dative and accusative plurals are built on the stem less its final -r and take -tri, -z and -ter; the vocative plural takes -ia on the shortened stem. Thus aevr, stem aetover: gen. sg. aetovun, dat. sg. aetovi, acc. sg. aetovas, voc. sg. aetovi; nom. pl. aetover, gen. pl. aetovetri, dat. pl. aetovez, acc. pl. aetoveter, voc. pl. aetovia.

nopl is honoured by the regular classes only; the irregular classes build their plural on a separate branch and ignore it. All three failure cases — an unknown class, a lemma without its class's ending, and an irregular noun with no stem on record — are returned as a class="error" span in place of the table.
