lausekkeessa

Lausekkeessa is the inessive singular form of the Finnish noun lauseke. Lauseke means an expression or phrase, and it can refer to a mathematical expression as well as to a linguistic or general phrasing. The form lausekkeessa literally means “in the expression” and is used to indicate location inside the expression or its content.

Morphology and spelling: The inessive singular is formed by adding the suffix -ssa to the word. For lauseke, this yields lausekkeessa, with the spelling reflecting the -e ending of the base and the ensuing -ssa suffix. This results in a double “e” before the suffix in standard Finnish spelling.

Usage: In mathematics and algebra, lausekkeessa denotes something that is contained within a particular expression, for example: “Lausekkeessa 2x + 3 x esiintyy muuttuja x.” In linguistics or general language usage, lauseke can also mean a syntactic phrase, and lausekkeessa would refer to that phrase within a larger construction.
