In a comment to a recent post, my number one of recent times commenter Batchman mentioned Monty Python’s Argument Clinic sketch. I used this in class many times to show the inter-relationship between verbs and nouns, in this instance, first, argue and argument, and also between the verb argue and the (I’m not sure what the technical term for this is) have an argument.
Many English nouns and verbs relate in one of four ways: either the noun is derived from the verb, the verb is derived from the noun, they are written the same but differ in pronunciation, or they are written and pronounced the same. In the sketch, we have at least one of the following words relating to speaking:
Noun derived from verb
argue > argument
contradict > contradiction
complain > complaint
Same written form, different pronunciation
abuse /s/ ~ abuse /z/
