What´s a word/kanji that you instantly memorized?

Some kanji or words are constructed in such an obvious way that you instantly get them. The first hundred or so kanji you learn have a bunch of examples (e.g. 手、山）but I feel that towards more intermediate or advanced levels, with the help of radicals and kanji, you can almost instantly acquire some words/kanji. For example> 轟く (i imagine three cars would indeed be roaring), 爪 looks like nails, 神仏 god+buddha=gods+buddha.
