Latin linearis

From līnea (“line”) + -āris. Doublet of līneālis.

The post-Classical sense of "having the form of a line" is likely a back-formation(Can this⁽⁺⁾ etymology be sourced?) from the adverbial form līneāriter (literally “using a line or lines”), which (along with līneāliter) was often used with verbs of motion, resulting in reanalysis as "like a line", from which follows the adjectival sense "line-like".
