Treat 鋴 as a rare variant in the 鎭/鎮 family.

The trail runs through two dictionaries: a note in 字彙補, a supplement on rare forms, calls 𨥵 an old form of 鎭 and says the 集韻 writes it as 鋴. That Song rhyme dictionary, conventionally dated 1039, is the earliest dated record of this glyph.

The family covers a weight for holding things down, calming or suppressing, guarding, and later towns — senses belonging to 鎮 itself, not a separate modern meaning for 鋴.

Why do dictionaries disagree about its reading?

The surviving records list different readings for the same glyph.

Han Dian lists Mandarin zhèn and Cantonese hak1; Taiwan’s 2024 CNS11643 record gives kè — matching 克, the right-hand phonetic. A real documentation split, not several everyday meanings.

In a real text, the surrounding word and source outrank any single dictionary line. For modern writing, use 鎮 or 镇.

Is 鋴 used in dialect writing?

Yes — in one recorded dialect word.

Taiwan’s 2024 Ministry of Education dialect table lists 鋴 inside 靐鋴, glossed “not refined”, citing the 上元縣志 county gazetteer. It marks the character 字書無 — absent from standard dictionaries — so the gloss stays with that phrase and source.
