The story

A hill (阝) heaped high (且) across the road: a barrier in your path. 阻む is to stand in the way, as when a rival 連覇を阻む, ends a winning streak, 阻止 is stopping something cold, and 阻害 is getting in the way.

Used in 阻む (habamu, to block/stand in the way), 阻止 (soshi, prevention/blocking), and 阻害 (sogai, hindrance)
