TERMINOLOGY:

-- "slot" = A particular combination of tense/mood/person/number/gender/etc. Example slot names for verbs are "pres_1sg" (present first singular) and "past_pasv_part_impers" (impersonal past passive participle). Each slot is filled with zero or more forms.

-- "form" = The conjugated Ukrainian form representing the value of a given slot.

-- "lemma" = The dictionary form of a given Ukrainian term. Generally the infinitive, but may occasionally be another form if the infinitive is missing. ]=]
