spanish grammar

Friends,hello again i have some difficulties in recognizing words in their past forms ,i can't find some of them in internet ,like amo(present) ame(simple past tense) amare(future) amaba(present continous) i request you to send here some verbs(most used ones especially) tense forms and any grammatical note that may not be found in everywhere.
Thanks in advance!

Aha! I was about to open a thread like this. Yes, I agree with gözde, it would be so nice if there are some grammatical notes and list of some words here. Of course if it won't be problem for Spanish friends

yes friends we will be very sorry if we cause you trouble,all we want is sharing of knowledge

Look at this link:
LEO Span.Konjugation - Verb

I know that its a German site, but its very easy to handle: just type in the verb you want next to the little lion above - a list of meanings in German will appear, but next to the spanish verb there is a little "i", click on that and then choose "span. flektionen" and it will give you all the forms in all tenses.
you can also type in a form of a verb (e.g. amaba) and it will give you the infinitive at the bottom with a little black point besides it.
give it a try!

Recognizing the tenses sometimes is hard. If you want to I'll explain how to form them step by step. Just let me know

preterito imperfecto ,what is it?

It is a past tense. In Spanish there are several past tenses. The most important ones are those:

Perfecto is used to express a past that has a relation to the present (e.g. today, this week, this year - a period of time that is not over yet even though the action is).
Example: Hoy he visto a mi amigo Juan.

Imperfecto describes the background in the past, what is always like that, regularly done etc.
Indefinido describes the actual actions in the past.
Example: Caminaba por la calle cuando de repente vi a Pedro.

Pluscuamperfecto expresses the past of the past, what had happend before other things happend.
Example: Ya había comido cuando llegó mi madre.

Did I explain it well? If you have any questions - just ask, it's fun to help

Ok I'm not spanish but I can help a little bit.
