Start a sentence with a conjunction?

Question

I am editing a manuscript for a woman before it goes to a publisher, and she starts several sentences with "but". Is it just my personal taste that is telling me that sounds awful? I am unsure of whether or not to include a comment about starting sentences with the word "but", or just to leave it be.

I should include that some sentences (for example "All I was able to think about was....") just SOUND wrong to me. I don't have a formal education in English, she only chose me to edit for her because of my writing strengths. Is that actually a poor word choice, or is that just my opinion?
(I would replace that sentence with "All that I COULD think about was.."). Help, I'm confusing myself.

Answer 1

That's some writer you got stuck editing. Starting a sentence with a conjunction is gramatically incorrect, and if you leave it in, it will not only reflect negatively on the writer herself, but it will reflect poorly on you for allowing it to be used. Now, if this manuscript is of dialogue, and such speech seems important or reflective of the character who uses it, then that may be an exception.

Answer 2

There really is no problem using a conjunction to begin a sentence where it is appropriate. However, it would be more desirable to use a range of appropriate conjunctions rather than same one frequently. I've included a link to a site that discusses the types of conjunctions and their uses.

Answer 3

It used to be very passe to begin a sentence with a conjunction. However, English grammar rules have become more lax in the last few years. And, now that you know that, you don't have to worry about it!! (<---conjunction started this sentence!)

Answer 4

I completely agree with you. Sentences shouldn't start with "But". She could use other words such as:

However
Although
Nevertheless
On the Contrary
Though
Still

Anything but BUT! no pun intended... :)

Answer 5

When used appropriately, it adds emphasis to the second clause.

But don't overdo it.
