2.) Write a draft that follows the guidelines from number 1, above. Get feedback on the draft from colleagues, supervisors, teachers, etc.--someone who has not read the longer work. See what questions they have and ask them to explain to you what they expect from the longer work. This will help you to see if the abstract is doing its job. Use the English grammar checker while writing the draft and the writing enhancement feature that serves as a vocabulary check.
3.) Revise the abstract based on the feedback. Plan to revise often to get it right and to keep it within the word limit. Be sure to use the WhiteSmoke spell check and grammar check while revising. Also, this is a good time to use the powerful thesaurus to suggest more effective language and the large dictionary to make sure that you are using each word correctly.
4.) Be sure your abstract is grammatically correct with correct spelling and punctuation by using WhiteSmoke English grammar check and spell check one more time!
