lóstrego

• lústrigo

Attested since 1370. Uncertain etymology. Perhaps from Latin lūstrō (“I purify; I illuminate”) from Latin lūstrum (“sacrifice”); or rather, given the stressed vowel /o/, from Proto-Celtic *lowkstriko-, from Proto-Celtic *lowko- (“bright, light”):[1] compare Welsh lluched (“lightning”) and North Catalan llaucet.[2] Alternatively, deverbal from lostregar, and this irregularly from Latin *lūstricare. Ultimately from Proto-Indo-European *lewk- (“to shine”).
