You should get used to it that a password should never be an existing word or a combination of words that could be in a word list there are plenty of word lists circulating on internet.
Such methods are known and used in password cracking programs. A possibility is to remember a phrase and use the first or second or last letter of each word in that phrase to form the password and if possible change some letters to numbers and include other symbols if they are allowed.
