Lemas

Lemas is a term with multiple meanings across languages and disciplines. In Spanish and Portuguese, lema means motto or slogan, and lemas is the plural form used for such sayings, frequently appearing in political, social, or organizational contexts.

In linguistics and lexicography, the term lemma (plural lemmas in English) denotes the canonical base form of a word, the form used to index vocabulary and to aggregate inflected variants. Some languages spell this concept with the word lema; its plural is lemas in Spanish and Portuguese.

In mathematics and logic, a lemma is a proven auxiliary proposition used to prove a larger theorem; the plural lemmas are common in English-language texts. In Spanish and Portuguese, the corresponding plural form for the same concept is lemas.

The term lemas therefore appears in dictionaries, mathematical and linguistic writings, and political discourse, depending on language and context.
