noun
Refers to a framework of crossed wooden or bamboo strips, often used in windows, doors, or partitions in traditional Japanese architecture.
古い町家の窓には連子がはまっている。
The windows of the old townhouse are fitted with latticework.
格子 is a more general term for lattice or grating, while 連子 specifically refers to a type of lattice with closely spaced vertical or horizontal bars, often used in traditional Japanese architecture.
The kanji 連 (connect) and 子 (child/small thing) together suggest a connected series of small bars, which describes the lattice structure. The exact historical derivation is uncertain.
