Conversely, words are synonyms.

Some words are made up of two words with similar meanings. If you read them backwards, the meaning is still the same. Such as: talk-talk, perception-perception, snuggling-snuggling, liking-joy, relaxing-slowing down, accumulation-accumulation, mutual-mutual, substitution-substitution, inquiry-inquiry, swallowing-swallowing, suffering-suffering, neatness-neatness.

After the words associated with some contents are reversed, their meanings are still similar or related, such as: accumulation-accumulation, midnight-midnight, boldness-boldness, qualitative change-deterioration, openness-liberalization, fireworks-flame, youth-snow-snow, well water, infatuation-infatuation, infatuation.

But there are still many words that are composed of two words with similar meanings, such as: production-generation, reality-realization, honesty-solar terms, calculation-calculation, face-face, official-eunuch, will-will, play-volatilization; Some words that are not synonyms can't be reversed casually, such as names-celebrities, getting on the horse-immediately, being in charge-possessing, flirting-emotional appeal, turmoil-walking, getting-getting, human feelings-lovers, rural areas-going to the countryside, stories-accidents, leaders-matchmaking, and Shanghai.

Another interesting phenomenon is that the names of some things, if reversed, just show the purpose of these things, such as: sheepfold-sheepfold, bedding-bedding, hammer-hammer iron, door lock-lock, lid-lid, cork, toothbrush-brushing, bedspread.
