Synonym discussion

Sense: adjective/1

These words all suggest that more than one element matters, but they are used in different ways. 'Multi-variable' is a general technical adjective for a model, system, or problem where several changing inputs must be looked at together. 'Multivariate' is the closest synonym, but it is more strongly tied to mathematics and statistics. 'Multifactor' usually stresses that several causes are involved, especially in medicine, psychology, or policy. 'Complex' is broader and less technical: a problem can be complex because it is difficult or tangled, even when people are not analysing it as a set of separate variables.

Etymology

LatinEnglish

Formed in modern English from the prefix 'multi-' meaning 'many' and the noun 'variable'. It became common in mathematics, statistics, engineering, and planning to describe cases where several changing inputs affect the same result and must be studied together.
