Members may kindly clear my doubtThere are so many words in English like this. Ant-eater, prevarication, metaphysics, parasychology, para-gliding, waterlogging, re-introduction, post-script, etc. The list is endless.
Yes, I am talking about those English words which are combinations of two words, or those words which become different words by prefixing 'meta', 'para', 're', 'post', etc. I would like to know whether it is absolutely necessary to use 'hyphen' in such words. As for example, should we write 'waterlogging' or 'water-logging'? Which one is correct: 'pre-varication' or 'prevarication'?
Is there any standard rule of using hyphen in case of such English words? Members may kindly clear my doubt.
