Q. I hate defining acronyms in the first paragraph of a paper because they impede flow. Therefore, is it acceptable to repeat the whole phrase, in this case, greenhouse gases, in the second use, and then define it there as (GHG)?

Q. I’m working on some writing that mentions “SQL servers.” I’m wondering whether I should go with “this data is stored on an SQL server” or “a SQL server.” I happen to be aware that “SQL” is usually pronounced “sequel,” which would lead me to write “a SQL server.” However, I worry that anyone unfamiliar with the term would assume each letter is pronounced individually—and it is very likely that the language I’m working with will be seen by many who are unfamiliar with SQL. What do you recommend?

Q. Is Q&A an acronym or an abbreviation? When using Q&A in, say, a training in PowerPoint, do you need to write out “Questions and Answers” the first time, like you would in an acronym, or does it stand on its own as Q&A?

Q. Hi, can you tell me what “pl.” stands for in “vol. 5 (1822), pl. 57”? Thanks!

Q. I’m wondering about omitting the periods for US Department of Energy. On its site, it’s U.S. Do we follow the department’s preference or Chicago style?

Q. What is the proper way to write Dr. Tom Smith Jr., M.D.?

Q. Will you provide examples of what is considered “humanistic” versus “scientific or statistical” when addressing the use of the symbol % or the word percent

Q. I just read your explanation of the use of Ms with a period as a shortened combination of Miss and Mrs. Boy are you wrong. Please read the feminist history and arguments of the early 1970s.

Q. Hello. A term you used in your hyphenation table is slightly incorrect, I believe. You call the units of measurement (m, kg, ft.) “abbreviations.” (I assume that things like MB and GHz also fall into this category?) According to Merriam-Webster, an abbreviation is “a shortened form of a written word or phrase used in place of the whole word or phrase. ‘Amt’ is an abbreviation for ‘amount.’ ‘USA’ is an abbreviation of ‘United States of America.’” That has nothing to do with the examples in the table.

Q. Greetings! When using a slash in the abbreviation w/ should there be a space after it or not? E.g., Fluffy went down the street w/Cookie? or Smoochie went to the store w/ Pookie?
