📏 寻 and 常 were both ancient length units; everyday measures = ordinary
寻 — hand 彐 (top) + inch 寸 (bottom), simplified from 尋
Originally a compound showing two hands measuring a length, with 工 and 口 between them, indicating the act of measuring with outstretched arms. The traditional form 尋 referred to a unit of length (about eight chi). The meaning extended from 'measure' to 'search for' or 'seek out'.
常 — 巾 (cloth) + 尚 (phonetic, 'esteem')
Originally written 裳, 常 was a phono-semantic compound: 巾 ('cloth') gave the meaning and 尚 supplied the sound, referring to a long lower garment or skirt. Over time the meaning shifted from 'everyday garment' to 'ordinary, regular, constant', while 裳 took over the original clothing sense.
