I have the following list:



l="apple","orange","kiwi","APPLE","lemon"


How can I make a command so the capitalised word would be returned?
So in this case the output should be



"APPLE"


Surely one can do l[[4]] but this is not what I am looking for, I want to have a command to search on a long list and return the capital words. Also note that in my case the whole word is in capital letter not only the first letter. Also assume that I don't know what would be the capital word, I just know that I have a list and somewhere in it there is a capitalised letter word, I need to find those.

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar.
