oh dear... there are many words which only have one meaning, for which you would have to work pretty hard to exploit this potential. off the top of my head, all of those -phobia words that relate to the fear of something specific (claustrophobia, homophobia, ailurophobia, triskaidekaphobia, etc.); -ology words which apply to sciences or studies of specific things (geology, ontology, vexillology [flags], pogonology [beards], pesematology [falling objects], etc.); descriptive words that have been coined to fill specific perceived gaps in the language (loghorrea, swoophead, yesternight, etc.) -- the list could get pretty long.
