I would like to know a total of 20 words each that can be made from the word Encyclopedia in the form of 3, 4 and 5 letter words.

I started you out with "relationship," but am not going to do your entire homework assignment for you. I'll give you a few for this word, but then you're on your own:

Three: pen, yen, den, can, nap, pad

Four: dial, clop, clap, clan

Five: cycle, panic
