障
zhàng
to block
to hinder; to obstruct
wall/mound (阝) + sound hint (章) = to block or obstruct
The left component 阝 represents an earthen mound or wall, grounding the idea of something physically standing in the way. 章 mainly contributes the sound zhāng; the meaning comes entirely from the barrier image on the left.
