used in transliterations
噶 is a rare kanji used primarily in phonetic transliterations, especially for foreign names and terms. Its standalone meaning is unclear, and it does not carry a distinct conceptual center beyond its use as a sound-representing character.
噶 is a modern character formed by combining 口 (mouth) with 葛, likely as a phonetic loan for transliteration purposes. The exact historical development is uncertain, but it appears to be a constructed character without a deep pictographic or semantic origin.
The mouth radical 口 suggests a sound, and the right side 葛 gives the phonetic hint. Think of 噶 as a mouth making a foreign sound for transliteration.
For カツ, imagine a cat's mouth making a sharp 'katsu!' sound as it transliterates a foreign name: katsu -> カツ.
