Gothic cardinal numerals
I think most of the Gothic words have been fixed now, so you can use them as an example. Category:Gothic numerals contains all Gothic words with the part of speech "numeral". It does not contain ๐ท๐ฟ๐ฝ๐ณ (hund, โhundredโ) or ๐ธ๐ฟ๐๐ฟ๐ฝ๐ณ๐น (รพลซsundi, โthousandโ), which are nouns (and have genders). ๐ฐ๐น๐ฝ๐ (ains, โoneโ) is also used as an indefinite determiner in Gothic, meaning 'any' or 'some', so it should probably have a separate header for that. The category Category:got:Cardinal numbers does contain both. That category should probably also contain the Gothic numeral symbols, which are Gothic letters that are used as numerals, as in Greek. I haven't added them yet.
So far I have only worked on the cardinal number categories. Ordinals will probably be more difficult because it is harder to determine what part of speech they are. In English and most Germanic languages they are adjectives, but I don't know about other languages. I wonder if there are any languages where ordinals are also grammatically "numerals" and therefore are interchangeable with cardinals.
