Right side is the simplified form of
巠 (jīng), the original phonetic in
經. The PRC reform stylised the upper portion into a
又-like shape, so the modern element looks identical to standalone
圣 (shèng, sage) but is actually a contracted 5-stroke form of the fuller traditional 7-stroke
巠 — different glyph history. Phonetic family in traditional:
經,
徑,
輕,
莖 — all jīng/qīng readings.
