TERMINOLOGY:
-- "slot" = A particular case/number combination (for nouns) or
case/number/gender combination (for adjectives). Example slot names are
"abl_sg" (for noun) or "acc_pl_f" (for adjectives). Each slot is filled
with zero or more forms.
-- "form" = The declined Latin form representing the value of a given slot.
For example, rēge is a form, representing the value of the abl_sg slot of
the lemma rēx.
-- "lemma" = The dictionary form of a given Latin term. For nouns, it's
generally the nominative singular, but will be the nominative plural of
plurale tantum nouns (e.g. [[castra]]), and may occasionally be another
form (e.g. the genitive singular) if the nominative singular is missing.
For adjectives, it's generally the masculine nominative singular, but
will be the masculine nominative plural of plurale tantum adjectives
(e.g. [[dēnī]]).
-- "plurale tantum" (plural "pluralia tantum") = A noun or adjective that
exists only in the plural. Examples are castra "army camp", faucēs "throat",
and dēnī "ten each" (used for counting pluralia tantum nouns).
-- "singulare tantum" (plural "singularia tantum") = A noun or adjective that
exists only in the singular. Examples are geōlogia "geology" (and in
general most non-count nouns) and the adjective ūnus "one".
