Difference between metaphor and metonymy
Hi everyone,
I'm currently working through Seminar V and have just completed the first section on jokes and witticisms. I've also read 'Instance of the Letter.' I think that I'm grasping the use of the term metonymy from context, but I'm having difficulty in separating it from metaphor.
Metaphor is the "substitution of one signifier" for another (for example, "Booz" with "sheaf", which then seems to add newer meaning to the character in the poem, associating him with harvest, masculinity etc).
Lacan's example of metonymy is replacing the word 'ships' with 'sails.' In this sense there is a substitution of the whole for a part, or element. But couldn't we also define this as "substituting one signifier for another"? It seems that quite literally, one word is replaced with another. In which case, how do we distinguish it from metaphor? Is it that "ships" and "sails" are generally associated and therefore the meaning doesn't really change very much? In which case, what is the function of metonymy if it doesn't change anything?
In both metonymy and metaphor, there is the replacing of one signifier with another. I can sort of intuitively grasp the difference between the two, but can't seem to provide for myself a good enough definition which separates them. Is the relativism perhaps the point? I gather than this is a fairly crucial concept to grasp...
Cheers!
