Journey
The word entered Western European languages through medieval Arabic astronomical texts. European translators misread the Arabic word 'samt' (meaning 'path' or 'way') as 'senit' due to a missing dot on the letter 'm' in the manuscripts, which solidified the form used in Latin and subsequently the Romance languages.
