1490: little and leprechaun Jan 10, 2019

Regarding the word 'leprechaun', the word is thought to come from 'lú' meaning 'small', and the latter half comes from the same root as 'corp'; read more about it in the link here. The first form, 'lú' is Old Irish, a Celtic language, but it is closely related to many words from Germanic languages, like the German 'lütt and lützel' or the West Frisian 'lyts', which all have the same vowel, even though it is written differently across the two language. Indeed, the original Old English 'lȳtel' is related, but that vowel isn't used for English anymore, so the similar one in 'little' is used instead today.
