<p>If I see "not only... but", is it an error. I always thought "also" was required, but today I was told that "also" doesn't always have to be there.</p>
<p>Is this true?</p>
<p>In modern written English “not only … but” (without the also) is acceptable usage. I doubt that the College Board would provide two choices which differed only with “but” versus “but also”. If they do, pick the “but also”.</p>
<p>See for example: [Grammar</a> Girl : Not Only But Also :: Quick and Dirty Tips ?](<a href=“http://grammar.quickanddirtytips.com/not-only-but-also.aspx]Grammar”>http://grammar.quickanddirtytips.com/not-only-but-also.aspx)</p>
<p>thanks @fogcity!</p>
<p>Ok, thanks for the help.</p>
<p>I was thinking more about identifying errors, not improving sentences.</p>
