'landlubber' originates from the English word 'land' and the obsolete term 'lubber,' where 'lubber' meant 'a clumsy or inexperienced person.'

'lubber' was used in Middle English to describe a clumsy person, and eventually combined with 'land' to form 'landlubber' in the 17th century.

Initially, it meant 'a clumsy person on land,' but over time it evolved to mean 'a person unfamiliar with the sea.'
