How do I write the plural possessive of the acronym COA in APA style (which in general doesn't allow for the use of an apostrophe)?
COA = children orphaned by AIDS
Children orphaned by AIDS [acquired immunodeficiency syndrome] sounds like it ends with an 's', but it actually ends with an 'e' (for 'syndrome').
So do I write: COA experiences, COAs experiences, or COAs' experiences
Which is the correct answer?
