立 — person standing on ground (大 over 一)
Pictograph of a person standing with arms outstretched on the ground line below. The original oracle bone form clearly shows a frontal human figure planted on the earth. The core meaning 'to stand' extended to 'establish, set up, erect.'
寄 — roof 宀 + strange 奇 (phonetic)
A semantic-phonetic compound: the roof radical 宀 suggests a dwelling or shelter, while 奇 (qí) supplies the sound, shifted to jì. The original sense was to lodge or stay temporarily under someone's roof, which extended to entrusting, depositing, and eventually sending or mailing things to another's care.
