Several parts combine into one character.

町 is a phono-semantic character: 田 (field) for meaning and 丁 (a nail, a T-shape) for sound. It originally meant the raised path or boundary between fields, but in Japan this character developed strongly into a word for an administrative district of a village or a block of a town.

Korean hanja-sound "jeong": rarely used in Korea today, though it left traces in colonial-era district names. It also appears in 町步 (jeongbo), an old unit of land area.

Mandarin: tǐng / dīng, a rare old agricultural term — barely seen in modern Chinese, met mostly when transcribing Japanese place names.

Japanese: on-reading チョウ (chō), kun まち (machi). 町 (machi, town / district), 町内 (chōnai, neighborhood), 下町 (shitamachi, the old downtown), 町長 (chōchō, town mayor). It is a core unit of the Japanese address system — the 町 (machi) in 市 (shi, city), 町 (machi, town), 村 (mura, village). The same machi can also be written 街, but 町 carries an administrative nuance while 街 suggests a bustling street.

Memory aid: a nail (丁) beside a field (田) — the town and street grown up along the paths between fields.
