Sometimes students think that this discussion of types of language is about vocabulary, but it's not. You don't need a fancy vocabulary to come up with bent spoon or limping dog or Mary told Margaret she hates me . It's not about imagination, either. If you have reached any kind of a reasoned conclusion, you must have had or read about or heard about relevant experiences. Finding concrete specifics doesn't require a big vocabulary or a vivid imagination, just the willingness to recall what you already know. If you really can't find any examples or specifics to support your general conclusion, chances are you don't really know what you're talking about (and we are all guilty of that more than we care to admit).
