I don't understand the A and Al or the optulea and the opta, when do you use them, does it have something to do with definite article and why is the substantiv/noun not definite article. Thanks! :-)

The only thing I know is that A is for female nouns and AL for male

[Mapka15]

And so is "opta" for female and "optulea" for male nouns

Somebody explain "mar, mare, mari"
