Is it grammatically correct to start a sentence with and?

Answer 1

Occasionally, it's OK. Usually seen this way in quoted conversation and in the press by careless writers who often misuse and misspell words.

More careful writing normally avoids this casualness by dropping the connecting word, ending the first clause with a period, forming a resulting sentence.

Then starting a new sentence for the second idea.

The formal use gives the reader a better impression of the writer.

Answer 2

Yes, it is grammatically correct to begin a sentence with "and" in informal or creative writing. However, in formal writing or academic essays, it is generally considered best to avoid starting a sentence with a coordinating conjunction like "and".
