Vamos a jugar!! Different gender? A different meaning!
Like the title says, some words will change meaning when they get another gender.
That is one of the many reasons why in Spanish the gender of words is very important.
The game goes very simple. Just tell us a word that has 1 meaning when it is feminine and a completely different meaning when it is masculin, or vice versa.
Easy ha?! 
When you have found a word, write down both genders with their meaning
I'll start with one as an example:
el cura ~ Priest
la cura ~ Cure
Goodluck,
and most of all
