I was told here several times, that a part of speech is not universal, but specific for each language as much as the A,T,C and G's are in everyone's genome.
Nethertheless, occasionally the same terms are used for in different languages for practical reasons, e.g. Adjective in English and Japanese, even though they are similar but not equal in all respects.
But what if you compare the parts of speeches of thousands of languages? Is it still the case, that no two languages have identical parts of speeches or could it be, that there is a limit for specific ones?
To draw an analogy, each language possess a subset of all phonetic sounds possible across all languages as described in the IPA chart, but the number of all sounds possible would have a limit, even if millions of languages existed.
Is there something like an IPA of the parts of speeches or another approach to describe parts of speeches with a closed set of universal features?
