遮断

syadan
mental block, blockage, to block, to intercept, to impede

I know the second character quite well, as it comes up in terms for interruption of Internet or other telecommunication connections, but I hadn't recognized the first character, which is why I thought to include this word here. 遮 is used, in verb form, as 遮る (saegiru, to intercept, obstruct).
