Learn English – for as – meaning

You should not say for another example.

The phrase for example does not tell the reader what you are about to say, it tells the reader why you are saying it. This is why we use the preposition for, just as we might say for better understanding or for comic relief, and it is why we do not say for an example. Example is not used as the 'countable' noun but as a generic quality attributed to what follows: it exemplifies what has gone before.

All four sentences are examples where "as" should be used. (d) is the only one that uses "as", so it happens to be correct.

• a) As I was saying before being interrupted, being polite is mandatory...
• b) I got a promotion! Now I work as a production manager, with my own room and a personal assistant.
• c) Nothing new to report. Same as last week.
• d) That is not enough. To finish the job, I will need at least three times as much.

All four choices are examples of semi-formal speech. They are all examples of things a "production manager" might say, either at work, or to his wife. Choice (c) does not use full sentences, but it is a natural way to give a status report. Unless the "production manager" is responsible for supervising a "room" in a factory or "boiler room", an American would say "my own office" instead of "my own room".
