Somar

Somar is a Portuguese verb meaning to add or to compute the sum of numbers. It is used in mathematics to indicate the operation of addition and more broadly to combine quantities or values in everyday language. The verb also appears in figurative expressions such as somar forças or somar esforços, meaning to pool resources or coordinate actions.

The word originates from Latin summāre, related to summa meaning "total" or "sum." Somar is a regular -ar verb and follows the standard conjugation patterns of this class. In the present indicative, it is: eu somo, tu somas, ele soma, nós somamos, vós somais, eles somam. The pretérito perfeito is formed regularly as: eu somei, tu somaste, ele somou, nós somámos, vós somastes, eles somaram. Other tenses follow standard -ar verb endings, making its conjugation straightforward for learners.

Usage examples illustrate its function: "Ao somar 3 e 5, obtemos 8." "Ela precisa somar os gastos para ver o orçamento." "Ele quer somar forças com o grupo deles." In computing and data processing, somar frequently appears as the summation operation; in software localized to Portuguese, the summation function is often labeled SOMA (or SUM in multilingual interfaces). The noun soma denotes the result of the operation, while somatório refers to the mathematical process or the summation symbol.
