These are the 15 largest islands by land area in or touching the Caribbean according to Wikipedia as of 6/7/2020 A.D. The link to my source is here: https://en.wikipedia.org/wiki/List_of_Caribbean_islands_by_area
In the case of some of the answers it was indeed necessary for the word island to be present. For example if "Baffin Island" was an answer than the type-in "Baffin" wouldn't make much sense. As for your grievance regarding my inconsistency I was simply quoting the answer from my source (which is in the description) as I had quite honestly never heard of some of these islands.
