I need good knower of english language, or translator

I need to know the meaning of some words.

First I must know the difference between words apricot and appricot?! Is the apricot same as appricot, since this other word have two p?! In some dictionaries it is stated that both words have the same meaning, but in some other dictionaries the word appricot does not exist?!

Next, what is the difference between words marmalad and marmalade, if any difference exist (I mean on difference like meaning and using of right grammar)?!

Also, what is the meaning of the word potsherd?!

And, what is the meaning of the word frige, does it have the same meaning as fridge?!

Thank you.
