IPA: /ˈlæsi/
KK: /ˈlæsi/
A young girl or woman, often used in a friendly or affectionate way.
The lassie danced happily at the festival.
The word 'lassie' originates from Scots, derived from 'lass' (meaning girl or young woman) with the diminutive suffix '-ie' (indicating small or endearing). Thus, 'lassie' refers to a small or dear girl or young woman.
Think of 'lass' meaning girl, and the '-ie' makes it sound affectionate, so 'lassie' is a term for a dear young girl.
