expression = express (semi-transparent) = express + ion

Regular nominalization, but the mathematical sense ('a group of symbols representing a quantity or relation') is a technical extension that learners may not predict from everyday uses.

Etymology

Expression comes from Latin parts ex- ('out') and primere ('to press'), like the English word press. In math, an expression is a group of symbols that together 'press out' or show a number or formula.
