Selected source glosses provide context, not a complete modern definition inventory

The noun is derived from fever-lurgy, possibly influenced by or related to lurk (“to hang out or wait”). Fever-lurgy is possibly a variant of fever lurden (“idleness regarded as a medical condition”), from fever + lurden, lurdane (“used as a general term of abuse for a person, especially one regarded as dull or idle: loafer, sluggard”). Lurden, lurdane is derived from Middle English lurdan (“coward; good-for-nothing person, fool, rascal; lazy person; low-born or ill-mannered person; unfortunate person; wicked person”), from Old French lordin, lourdin, from lourd, lourt, lorz (“clumsy, oafish; heavy”) (modern French lourd) + -in (suffix forming derogatory or diminutive nouns); and lourd from Late Latin lordus, lurdus (“clumsy; heavy slow; stupid”), probably from Latin lūridus (“sallow, wan; ghastly, horrifying”), possibly from lūror (“lividness; paleness, pallor”) (possibly ultimately from Proto-Indo-European *(s)leh₃y- (“bluish”)) + -idus (suffix meaning ‘tending to’ forming adjectives). Noun sense 1.2 (“non-specific disease”) was popularized by the British radio comedy show The Goon Show (first broadcast 1951–1960), especially the episode “Lurgi Strikes Britain” (series 5, episode 7; 9 November 1954) written by the Anglo-Irish comedian Spike Milligan (1918–2002) and the English comedian Eric Sykes (1923–2012), about the outbreak of a highly dangerous and infectious and—as it turns out—fictitious disease known as “the Dreaded Lurgi” created as a scam. Another suggestion is that the word is a corruption and contraction of allergy, but this is a folk etymology as allergy has a soft g (/dʒ/) while lurgy has a hard /ɡ/ (rhyming with Fergie). The adjective is probably from an attributive use of the noun.
