Yeah, I wasn't too specific about all of them, was I?... Sorry.
I will re-post them below, with gender forms added.
In Spanish, most words denote their gender by ending in "A" or "O". When a word is neutral, it normally ends in "E" or a consonant. Of course, there are exceptions to the rules. One very clear exception is the word "POLICIA" (police), even though it ends with an "A" it is also used to refer to males: EL POLICIA= the policeman LA POLICIA = The policewoman.
