Hi Farhana In your question you ask if the sentences are "grammaticality correct" and "natural". The second part of that is always a little bit subjective. For me I think Adam's response creates grammatically correct sentences... but they don't seem very natural. In my opinion it doesn't feel right to use 'postpone' when talking about 'salary' payments. I'm fully aware of the fact that different types of English exist in different parts of the world, so I did a quick internet search for examples that use these two words together. I only found a few examples from India and Malaysia. I checked the Collins Cobuild website. This gives examples of collocations that occur in the language. It seems that this website confirms my thinking. I think it would be much more natural to use the words 'delay' or 'defer' when talking about salary. Also do you mean that the payment was delayed temporarily? Say for example the person normally receives $1000 every month, do you mean that for the month of March they received zero but next month (April) they will receive $2000? Or do you mean that they received nothing and in April they will get $1000?

1) His salary for this month was postponed for not being able to sing the national anthem. 2) His salary was postponed for one month for not being able to sing the national anthem. I modified both above slightly to make them correct. In either case, I think perhaps "postpone" isn't quite the verb you want. I believe "suspend" is better for this meaning. The context suggests to me that he will never get paid for this month at any time---thus one month's pay was suspended. People will probably understand "postpone" to mean the same thing, but I don't think it is the standard way to say this.

It’s not clear what you mean. Is his salary just for singing the national anthem? Was he penalized for not singing the anthem once even though he did other parts of his job? He was unable to sing the national anthem and was docked a month’s salary as a result. He was docked/penalized a/this month’s salary for failing to sing the national anthem. They withheld a month’s salary for his failure to perform the anthem. As to the ‘postponed’ issue, it’s fine to say that payment of salary can be postponed. But salary can’t be postponed. And you are

#1: omit "of" - otherwise good #2: good sentence If his salary is merely postponed, there is no penalty. It means he will receive his salary late, but he will still receive the same money. Is that what you want to say?
