阻む
はばむ · habamu · JLPT N1 · verb-godan
to stop
🚧 阻 = block with a door (阝 hill/wall) and 且 stacked; 阻む = a wall or barrier that stops you from going forward
Kanji 阻 has the 阝 (mound/wall) radical, so it means a barrier that blocks passage. Use it for stopping someone or opposing them: 夢を阻む, to keep a dream from coming true.
