Nandagopal I don’t know as an Indian, why you speak with such authority on this subject as you sadly misplaced this. Why did Self come along like that, even though it’s the prefix of self, it’s used? There is no independent word self in English (except as a noun in areas such as psychology). Self -service is the only correct form in standard English. Why should prefixes be listed as being prefixed to the word they refer to to (with a hyphen or directly attached). Is it possible that word/s might be better to stand

alone as they are not words?
