Learning German I'd write flashcards with summer on the front and der Sommer on the back. However, learning Italian, the back would say l'estate, with no way to tell whether the word is masculine or feminine. Is there a good way of solving this problem that I haven't thought of?
Of course I could write estate (f), but it adds a step in the thought process and feels unnatural. I could also write la estate but maybe that would even be detrimental to my Italian.
