"Other" implies a selection to the exclusion of something else - a choice between two or more things. "Another" means something additional to something. It is sometimes used in spoken English to mean "other" but it is not strictly correct. "How about a light beer?" "No - some other beer besides light." (The speaker wants a different beer from light.) "I've finished this beer. Could I have another?" (The speaker wants one more of the same kind of beer) As for "each" and "every" they can sometimes mean essentially the same thing, but not always. "Every person here has a name" is the same as "Each person here has a name." However, there are difference. "Every" can refer to a range of possibilities. "He was given every chance." - You could not say "He was given each chance." Each can also be used as "apiece". "They cost a dollar each." You might be able to say "Every one is a dollar." but you wouldn't hear that too often.

Oh, thanks that was interesting for me too!

He turned to talk to his other friend and then another one. Each and every man has a weakness .

other = something else another = one more of the same thing each = all every = all
