McCain: Half-Baked, 'Spurious' Nationalism
Spurious rode to the top of our lookups on October 17th, 2017, after Senator John McCain employed this adjective as a way of modifying and decrying present-day nationalism.

Spurious comes from the Late Latin spurius (“false”), which in turn had the earlier Latin meaning “of illegitimate birth.” Although the word did have that meaning early on in its use in English, it appears that its initial use to mean “false” or “deceitful” was in senses unrelated to familial ancestry.

The senator from Arizona was, we presume, using the word in its "of a deceitful nature or quality" sense, rather than impugning the parentage of the word nationalism.
