婧 (jìng) describes a slender, upright, graceful woman — an elegant and relatively uncommon character that gives the name a literary feel. Note the pinyin jìng (fourth tone), not the more common jīng/jǐng.
mistakes
Don't mix up 婧 (slender/graceful) with the homophone 静 (quiet) or 靖 (pacify) — all read Jìng but carry different nuances in names.
