TERMINOLOGY:

-- "slot" = A particular combination of case/gender/number.
	 Example slot names for adjectives are "gen_f" (genitive feminine singular) and
	 "nom_mp_an" (animate nominative masculine plural). Each slot is filled with zero or more forms.

-- "form" = The declined Slovak form representing the value of a given slot.

-- "lemma" = The dictionary form of a given Slovak term. Generally the nominative
     masculine singular, but may occasionally be another form if the nominative
	 masculine singular is missing.
