I was looking at an Android app, there are two buttons with these names: "Choose Suspect" and "Send Crime Report." After I thought about it, there are bunch of places where 'a/an' are omitted and they look just fine.
So, when is it safe to omit a/an? What's the mental model?
I checked another question with similar title - "When do you omit a, an or the?" - which deals with omitting articles after 'of.'
