Interference
Intervention
noun, verbal noun
When you're fording a stream, and you suddenly feel dry feelings around you, that doesn't make any sense for something wet. This dryness is an interference. It's an intervention trying to stop you from fording.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
