In honour of International Women’s Day, I thought it would be good to sort out the confusion between woman and women. If this little memory trick helps, please feel free to use it. The letter A is the first letter of the alphabet—letter number ONE. So if you are talking about only one woman, use an A. The letter E comes later in the alphabet, so more than one. E also looks like a backwards 3 which is also more than one. If you are talking about multiple women, use an E.
