lassie
UK[ˈlæsi]US[ˈlæsi]
n
A girl or young woman (used especially in Scotland and Northern England).
n
A female dog, especially of a collie breed.
Etymology
The word 'lassie' originates from the Middle English term 'las', meaning 'a young woman', which itself likely has Old Norse origins, possibly related to the Swedish dialect word 'lask', meaning 'an unmarried woman'. The addition of the diminutive suffix '-ie' (a common feature in Scots and Northern English dialects) created 'lassie', a term of endearment for a girl or young woman. This affectionate connotation was famously extended to a fictional, heroic female collie dog in literature and film, which subsequently popularized the term as a generic, informal name for a female dog, particularly of the collie breed.
Analysis
This word is a simplex, derived from a diminutive form of the Middle English word 'lass'. It is not productively formed from multiple independent morphemes in modern English.
