Origin: Of multiple origins. Partly a borrowing from Latin, combined with an English element. Partly formed within English, by derivation. Etymons: Latin ēlīmināt- , ēlīmināre , -ion suffix¹; eliminate v., -ion suffix¹.

Etymology: Originally (in sense 1) < classical Latin ēlīmināt-, past participial stem of ēlīmināre eliminate v. (in its specific sense ‘to divulge (secrets)') + -ion suffix¹ (compare -ation suffix); compare slightly later eliminate v. 1b. In later use < eliminate v. + -ion suffix¹ (compare -ation suffix).In senses 2a and 3 perhaps after post-classical Latin elimination-, eliminatio expulsion (9th cent. with reference to people, 13th cent. with reference to things). In sense 2b after French élimination (1805 or earlier in this sense). With the specific use in mathematics (see sense 5) compare French élimination (1765 in this sense).
