👥 陪 = 阝(mound) + 咅 (péi phonetic) — escort someone up the hill
The 阝 radical on the left is a small mound or place; 咅 on the right supplies the péi sound. Semantically it shifted to mean accompany or keep company — to escort someone alongside.
陪 — mound radical 阝 + 咅 (phonetic)
陪 is a phono-semantic compound. The left 阝 (mound/hill) originally suggested earthen embankments piled alongside something, while 咅 supplies the sound. From 'an accompanying mound of earth' the meaning shifted to 'to accompany' or 'keep company with,' the standard sense today.
