Similar

TakaIs it really so?

I see nothing wrong with it (as long as that sentence is preceded by the mention of at least one similar characteristic). What does your book say should replace it?

It says it should be either "similar+noun (pl)" or "other+noun(pl)" since "similar" itself implies others. And it goes on to say that it's the same kind of mistake as these below:

·nearly almost
·other fellow passengers
·return back
·repeat again

TakaIt says it should be either "similar+noun (pl)" or "other+noun(pl)" since "similar" itself implies others

Yes, without the context I suggested above.

Let's say a friend of mine has made a mistake. Then if I said to him "Don't make other similar mistakes", would it sound redundant and awkward as those examples above?

Yes.

Taka awkward

No; it is a common natural utterance. The spoken language in particular is rife with redundancies: it is a communication aid.

Good.

One more thing. About "repeat again". Isn't it that it's not wrong but it sounds awkward to mean a single repetition and that it means a different thing?

That is indeed a conundrum.

Really? Is it that difficult?

You repeat and end the repetition. And you start the next repetition. You have repeated again.

I thought it could be interpreted that way.

TakaI thought it could be interpreted that way.

Of course it can, but many will argue that 'again' remains redundant there.

Mister Micawber but many will argue that 'again' remains redundant there.

Will they? If you want someone to conduct the second doing after he ends the first doing, I think you will say "Do it again."

How would you say it if you want him to do the second repetition?
