Deliver
📦 送 (deliver) + 到 (arrive) = deliver-to-arrival, i.e. deliver
送 means send/deliver and 到 means arrive or reach a destination. Together 送到 emphasizes delivery all the way to the endpoint — not just sending off, but successfully reaching the recipient.
送 — 辶 (walk) + 关 (simplified from 灷, fire/torch)
Originally depicted hands holding a torch to escort someone on a journey, combined with the 'walk' radical 辶. The right side 关 is a simplification of an older form showing fire being carried. The core meaning evolved from 'escort/see off' to the broader sense of 'send' or 'give as a gift.'
到 — 刂 knife + 至 (phonetic, 'arrive')
到 is a semantic-phonetic compound. 至 ('to arrive') gives both meaning and sound, while 刂 (knife) was added later, likely as a phonetic reinforcer or to distinguish the written form. The core sense 'to arrive, reach' comes directly from 至, and 到 has carried that meaning since early script forms.
