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.
