Hi Carter, I assume that you are trying to say that words can be transformed between word classes by adding certain suffixes. For example: Wonder (noun) --> Wonderful (adjective) by adding suffix -ful Plenty (noun) --> Plentiful (adjective) by adding suffix - ful Read (verb) --> Readable (adjective) Move (verb) --> Movable (adjective) Attribute (verb / noun) --> Attributable (adjective) The suffix -able imparts the meaning of "capable of" or "have the characteristic of". Hope this helps. Cheers, Lance
