Usage notes

 * hẻm in Vietnam are (usually narrow) roads that lead to a dead end, and they are numbered, not named like open streets. Some streets that are so tight they're not eligible for being named and covered in asphalt may also be considered "hẻm".
 * Unlike true alleys, which are often concrete walkways or footpaths, hẻm can still be paved with asphalt and open for vehicular traffic.
 * For a figurative "dead end", use instead.

Adjective

 * 1)  narrow
