Lemma Facts apply to the concept in every language

No lemma facts recorded for this lemma yet.

How this concept is organized, independently of language: a discrete entity (cat, idea), material or a quality without inherent units (water, justice), or an aggregate of members (furniture, collected data). This does not determine grammatical countability.
Whether this concept denotes material entities/material (physical), or informational, mental, social or conceptual referents (abstract). Classify the referent, not its physical representation.
A person noun that itself names a man or a woman (boy, mother, husband). Its counterpart is a separate lemma, so it has no male/female gender variants; absent for every other noun.
