I also thought "the" would be applicable here. I suppose I am getting tripped up by the "an" in "ann an". "An" is the definite article, but it seems in this phrase it doesn't convey definiteness as it usually does, right? Is there a specific grammatical rule I can reference and familiarize myself with to better recognize when "an" doesn't equate to "the"?
If not, it's just something I need to be aware of when using this construction.
Ann an was introduced in the lesson About Me. For one sentence, a contributor explained in the comments section that Ann an should be seen as a construction, meaning in, rather than two distinct words. Thus, an has nothing to do with the when preceded by ann.
