Short for cul-de-sac, referring to a dead-end street or passage. Used informally in real estate and urban planning contexts.
Abbreviated from French 'cul-de-sac', literally meaning 'bottom of the bag'. The French term was adopted into English in the 18th century for anatomical dead ends, then extended to streets.
This truncation shows how language naturally shortens frequently used terms for efficiency. While 'cul-de-sac' sounds elegant and French, 'cul' has become the practical shorthand used by real estate agents and residents who live on these quiet, family-friendly streets.
