If you are talking about Animal Crossings City Folk, then you can't get bigger pockets. You can save letters in your letter holder and put things in letters and remove them later.
A seven letter animal called a Panther can have its last four letters removed to form the word PAN, which can be used for cooking!
Fox - Take away the F and it's Ox :)

You cannot make a bigger word using the letters in 'responsibility'.To make a bigger word, you must add a letter, and since you cannot add a letter, and can only use the letters you have in 'responsibility', you cannot make a bigger word. You can make 0 bigger words.
