The Cambridge Latin Course Dictionary lists the words pauci, paucae, pauca which I assume are adjectives, and it is defined as "few, a few". I cannot find this listing in the same form on wikitionary, which instead defines it as an adjective paucus, pauca, paucum meaning few, little. Now, this in itself is strange, but then I searched up the term in Latdict (online dictionary) and it came up with this: paucus, pauci (noun) with a definition of "a few" and masculine. Latdict also supplied another noun on the same search, (this time neuter), paucum, pauci meaning "only a small/an indefinite number of/few things (pl.), a few words/points".
What I want to know is whether there are multiple words, or these are the same words except with different forms, and what the correct (actual) forms of these words are.
