送行

to see someone off
👋🚶 送 (send/deliver) + 行 (go/travel) = send off someone who is going
送 means to send or deliver, 行 means to go or travel. Together they literally mean sending someone as they go — waving goodbye at the airport or throwing a farewell party before a trip.
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.'
行 — crossroads pictograph (left 彳 + right 亍)
行 originally pictured a four-way crossroads in oracle bone script, with two paths meeting. From 'road' it extended to 'walk, go, travel,' and then to 'a row, line' or 'business firm' (read háng). The two halves 彳 and 亍 are the split sides of that ancient crossroads.
