avaldises

Avaldises is the plural form of avaldis, a Latvian term used chiefly in mathematics, logic, and computer science to denote an expression: a syntactic form that denotes a value or can be evaluated. The singular avaldis is used for an individual expression, while avaldises refers to multiple such constructs. The term appears in technical Latvian texts, manuals, and curricula to distinguish expressions from other linguistic units such as statements or phrases.

In mathematics, an avaldis may consist of numbers, variables, operators, and parentheses, for example 3 + 4, x^2 + 7x, or (a − b)/(c + d). In logic, it includes propositional forms built from variables and connectives, such as p ∧ q or ¬r. In programming and computer science, an avaldis is any syntactic fragment that evaluates to a value, including arithmetic, relational, boolean, and function-call expressions.

Operator precedence, associativity, and type rules determine how avaldises are evaluated. Some languages perform implicit type coercion, while others require explicit casting. The term is typically reserved for formal constructs; in everyday Latvian, the more common word for a natural-language phrase or clause is izteiksme. Translators usually render avaldis as "expression."
