Accordign to the wiki though, there are two acents and they can be used to differenciate singular and plural or unrelated words. That is to say, there exist minimal pairs differing only in which tones is used.
That wiki page (btw, obviously written by someone quite partial) itself says "Limburgish distinguishes two tones in stressed syllables
" which would mean it's a pitch accent language, like Boes says.
Minimal pairs like those cited routinely exist in pitch-accent languages (if they didn't exist there would be no point in talking about phonemic pitch):
tomten(tone 2) = Santa Claus; tomten(tone 1) = the garden
anden (tone 2) = the spirit; anden (tone 1) = the duck
It would appear that the claim that the pitch accent system of Limburgish is the most developed in Europe could be defendable, but nothing written on that wiki page suggests the existence of genuine lexical tone of a kind found in, say, Yoruba.
Since this means tone is phonemic isn't that the definition of a tonal language, or does it require that every syllable be tonic?
The latter, broadly speaking, is true.
