'condo' originates from the word 'condominium,' which comes from Latin, specifically the word 'condominium,' where 'con-' meant 'together' and 'dominium' meant 'ownership.'

'condominium' transformed into the shortened form 'condo' in modern English usage.

Initially, it referred to joint ownership, but over time it evolved into its current meaning of an individually owned apartment within a complex.
