Also and too can be used interchangeably in most cases. For example: I like cookies too I like cookies also. Both too and also are used for additional commenting. Examples: I like candy. I like cookies too. I like candy. I like cookies also. Sam: Do you watch Law and Order? Jean: I do watch Law and Order. Sam: I watch it too/also. Give me back my flashlight. Also give me back my watch. //also can be used at the beginning of a sentence but too can not. It would be wrong to say: "Too give me back my watch" but you could say "Give me back my watch too." Both too and also can be used at the end of a sentence. Too is the preferred informal word to use instead of also. The only real case to avoid using too, and instead you would say also, is if you already have a "to" or "two" in a sentence. For example: I would like two cookies too. I would like to go to Asia too. instead say: I would like two cookies also. I would like to go to Asia also. Too can be used to describe extreme extent. Also can not be used in these cases. Examples: That hat is too big for her head. She ate too much. "Even" does not have the same meaning as "also" and "too" and is used in a different context. Even is used to mean in spite of, although, despite, etc. Generally even is followed by though: even though. For example: I like chocolate cake, even though I do not like cake. I eat watermelon candy even though I do not like watermelon. Even does have cases where it seems like it is like "too" and "also". For example: I will add a remote, I will add a television, I will even add a cellphone to your purchase. sentence meaning: I will add a remote and a television and despite giving you both a remote and a television, I will add a cellphone to your purchase. In this case it might seem like it is like "too" and "also", however, the meaning is still despite/although with a hint of "too"/"also. Hopefully too, also, and even are less confusing.

you can say 'too', like this: it's too far, it's too late this is word(too) like very, maybe:) 'also' it is when you want to say 'and i also like drink cola'
