Dear Members: I'm new in this forum, I'd like to say hello to everyone and, of course, I'd like to put my first question: it's about masculine words ending in "a". If I'm not wrong (please correct me!), in Croatia people say: arhiv, biciklist, demokrat, fronta, gitara, gripa, minuta, pojava, planet, riža, soja, turist. In Serbia, people say: arhiva, biciklista, demokrata, front, gitar, grip, minut, pojav, planeta, riž, soj, turista. And it's agreed by all: kolega, sluga, ustaša (the word, I mean), poglavica, vođa, and vladika. I'd like to kwow whether this list is correct and ...which is the rule for adding or not this "a". Velika hvala.
