I feel silly asking this but I can't find the answer anywhere (including CMOS, dictionaries, etc.). I am a professional editor and am struggling with an author who uses "being" in the following way:
*He has a sleeve of tattoos on his left arm—the most prominent being a picture of Bettie Page.*
I mostly see this usage in romances or with British authors. What is "being" and why should I not change it to "is" to retain her phrasing.
Thank you!!!
