We shouldn’t have to tell you to run your cover letter through spell-check, but here’s an even better step: Check out how the wording sounds to others using Hemingway . Drop your text onto the page, and the color-coded app will give your writing a once-over. Is a sentence too wordy, overly complex, or totally unreadable? It’ll be highlighted in red until you revise it. Tend to overuse the passive voice? Every instance of it will show up in green. The site will even recommend when you can use shorter or simpler words (Why take up precious resume space with “utilize” when you can say “use?”).
Dear Li Mei,
Thank you for your comment and for your question about whether to use a period (full stop) after the abbreviation for Doctor. The answer depends on whether you are writing in American or UK (British) English. If you are writing in American English, you use a period: “Dr.” If you are writing in UK English, you do not use a period: “Dr”. In my opinion, while it is important that your manuscript be formatted in the correct language style, your cover letter can be in the style most natural to you (American or UK). However, if you want to be completely consistent, then you can prepare the cover letter in the style required by the journal.
