So does that mean instead of having tons and tons of rules in your context - free grammar you just have these base constructs and then a general mechanism for coercing them.
Yeah.
Mm - hmm. So that , you know , for example , uh , in the metaphor case , that you have a kind of direct idea of a source , path , and goal and any metaphorical one  and abstract goals and all that sort of stuff   you can do the same grammar.
Mmm.
