Additional notes

Welsh

I needed Welsh for a personal project. I also added Chechen since was on it.

The Welsh function has two additional arguments: gender (valid values fem or masc) and the counted object. The latter is needed since in Welsh the counted object does not follow the number (like English seventeen dogs) but is inserted within the numeric expression:

dau gi  ar bymtheg
2   dog on 15

e.g. num2words(17, lang="cy", counted="ci", gender="masc")

Currencies are used in the same way

E.g. num2words(31.50, lang='cy', to="currency", currency="GBP")

tair punt  ar ddeg, hanner cant    ceiniog
3   pound on 10     half   hundred penny

After a numeral the noun is always in Singular

Chechen

The Chechen API as also two language specific arguments, case (valid values: abs, gen, dat, erg, instr, mat, comp, all, obl, attr) and the semantic class (gender). The cases obl is needed when the numeral is used with a noun in non-Absolute Case, attr is needed (only internally) if the numeral precedes another numeral (ши бӀе == 2 * 100). All other cases are used if the numeral is used as a noun (Tree are coming) Chechen has 6 classes (genders) which are marked by 4 letters ("д", "б", "й" or "в".

class	SG	PL
1	в	д
2	й	д
3	д	д
4	й	й
5	б	б
6	б	д

Adjectives, numerals and verbs agree with the noun in class. In case of numerals it is only 4, 14, 40, 80 which show the class letter. If not given "д" is used:

e.g. num2words(4, lang='ce', case="abs", clazz="в")
