You can use the yo, etc but then you are emphasising the person.

thus hablo = I speak, but yo hablo means more like ' Me, I speak '

With most languages, context is king, and emphasis is all.

For example, in hablo, emphasise the 'a' and it means 'I speak', emphasise the 'o' and it means 'he spoke'.

With languages I find that you go thru a grammar phrase where in order to learn the correct sentence structure you have to learn the grammar of it, but once you have learnt it, you then forget the grammar, often to the point where you can be hard pressed to remember why that particular sentence is the way it is.

I have just received a mail with some pictures that prove that the doors are always opened only for those who belive in theirselfs, so, we can do whatever we really want to and this dog shows us

Maybe bil is right when he said "the grammar is very important" if i had known it i would have written "themselves" instead of "theirselfs"
thanks a lot bil to correct me, things like that help me to improve my English

Hell, if I spoke Spanish as well as you speak English, I'd be very pleased.

of course...........but I am talking about complete beginners

after a while it goes in and they can understand - usually they can understand before they can speak, anyway
