I have a question about the etymology (within the Uralic family) of three Hungarian morphemes
- Accusative -t- suffix: Hungarian has an accusative in -t- (eg. fíu, fíut), which has no cognates in any of the Uralic languages that I am aware of, which have accusatives in -n- or -m-. Wiktionary states that this suffix is
"Of debated origin. According to the most accepted theory, it is from a possessive suffix that originated either from a *t-initial demonstrative pronoun or from the Proto-Uralic *tȣ̈ (“you”) personal pronoun".
The cited source is in Hungarian, which I cannot read. How could a possessive suffix evolve into an accusative marker? Has this happened in any other languages?
First person verbal -k- suffix: Regular verbs in the present tense indefinite conjugation take a suffix -Vk to mark 1st person singular. I can't find cognates for this in any other Uralic language, while Wiktionary offers no explanation either. What is the origin of this 1p marker?
Plural -k-: Hungarian also has a plural marker in -k-. (eg. kéz, kézek). This contrasts with -j- or -t- plural markers in most Uralic languages (although there do seem to be traces of a -k- plural in Samic languages, although only in the Nominative).
