Affix entry for "-ability" word suffixes?

[uncenter]

I'm not sure where else to put this but I'm curious about why there isn't an affix entry for the "-ability" suffix. Seems to come up a lot and is present similarly to the existing "-able" suffix. It might be that we can add "ability" as an additional replacement for the "-able" affix entry if the matching pattern can be sufficiently correct?

I think they originally came from Hunspell and its goals are to make the dictionary compact. Our goals were to add grammar metadata.

But they definitely do cross over because affixes impart certain parts-of-speech upon the derived forms they create. -able creates adjectives from verbs and -ability creates nouns from verbs.

I think Hunspell did some kind of cost benefit analysis to decide on which set of affixes would end up minimizing the dictionary size and thus limited the set of affixes they used.

This is from vague fuzzy memories from long ago when I played with spellcheckers.
