There are several kinds of words in reverse order, which are urgent.

1. Some words are composed of two words with similar meanings. If you read them backwards, they mean the same thing. Such as: speech-speech, awareness-awareness, snuggling-snuggling, mountains and rivers, relaxation-relaxation, accumulation-accumulation, mutual-mutual, inquiry-inquiry, annexation-annexation, neatness, vitality and simplicity-simplicity.
