quick grammar question

<p>hey is it grammatically correct to begin a sentence with "Because"... to know for sure for sat writing... thanks</p>

<p>Well, if it's something like "Because I can't write." it's a fragment. It is grammatically correct to say "Because I couldn't run, I walked home." You need that second clause.</p>

<p>i think it's correct if yoiu're saying something like "Because of the population increase over the last decade, unemployment has skyrocketed" or somethingl ike that... but not if you're saying "Because she left school early."</p>
