What does the abreviation INFLNFL stand for? What is the meaning of INFLNFL and where does it appear in the syntactic tree-construction?
I'm not sure it's the same, but I've seen this sort of annotation used quite a bit in Spanish. It's also a characteristic of the language though, even outside the world of linguistics. 'Los Estados Unidos' is often shortened to 'los EEUU'. Here is an excerpt from a website on Spanish syntax, in which the author refers to SN (sintagma nominal) in its singular & plural form as such: 'los SSNN' (los = plural, definite article) /'un SN' (un = singular, indefinite article). SN (sintagma nominal) is just the Spanish equivalent of the English NP (noun phrase).
