Termos

Termos is the plural of termo, a word that in Portuguese has several different meanings depending on the context. Among its widest uses are linguistic terms, mathematical terms, contractual terms, and the household item known as a thermos. The diverse meanings reflect how the same word can function as a unit of meaning, a mathematical object, a set of conditions, or a common name for an insulated container.

In linguistics and everyday language, termo refers to a unit of meaning or a lexical item—essentially a term or word. Phrases such as termos técnicos (technical terms) or glossaries of terms are common in dictionaries and specialized fields. The plural termos is used when discussing groups of words or expressions.

In mathematics, termo denotes a single element of a sequence or a term in an algebraic expression. For example, a polynomial has terms, each with a coefficient and a variable, and a sequence has a general term (termo geral) that describes its pattern. The concept is central to operations on sequences, series, and polynomials.

In legal and contractual contexts, termos refers to the provisions, clauses, or conditions of an agreement. Expressions like “em termos do contrato” or “termos e condições” indicate the specific commitments and rules agreed upon by the parties involved.

The common household object known as termos, a widely used insulated bottle, is designed to keep liquids hot or cold for extended periods. It typically features double walls with vacuum insulation, a cap or stopper, and comes in various sizes for home, work, or travel use.
