PartType: particle type
Types of particles found in various tagsets. I am merely presenting here what I have in Interset now. We will have to make it match our new definition of particles.
Mod: modal particle
Examples: [bg] май (possibly), нека (let), [cs] ať, kéž, nechť (let)
Emp: particle of emphasis
Examples: [bg] даже (even)
Res: particle of response
Examples: yes, no
Inf: infinitive marker
Did we say that these are subordinating conjunctions?
If so, do we want to have this feature value in “conjtype”?
Examples: [en] to, [de] zu, [da] at, [sv] att
Vbp: separated verb prefix in German
They are analogous to verbal particles in other Germanic languages, which again overlap with adpositions and adverbs. Do we want to tag them as adpositions/adverbs and add this feature? Examples: [de] vor (in “stellen Sie sich vor”)
Besides these, various languages have also question particles (they cause the sentence to be question, i.e. thye are a sort of pronounced question marks) and negative particles (English “not”, German “nicht” etc.; some people would say that these are adverbs). I have been abusing “prontype” values “int” and “neg” to capture these two types in Interset but I am not particularly happy with that, as prontype otherwise applies to different class of words. So if we keep the “PartType” feature, we may want to also add the “int” and “neg” values here.
