quatre (Catalan)
Where does "quatre" come from?
The Catalan word 'quatre' traces its roots directly to the Latin 'quattuor,' meaning four. This Latin term itself evolved from the ancient Proto-Indo-European *kʷetwóres, a common ancestor shared by many languages, including the English word 'four.' Over millennia, the word has maintained its core numerical value while adapting its spelling to the unique phonetic patterns of the Romance languages.
