Esoteric?

Peter is dumb. That's all I need to say to set up this FG quote.

Lois: It's geat they picked your theme, but isn't it a little esoteric?
Peter: Esoteric?
(Zoom in to the guys in Peter's brain)
Guy1: Could it mean sexy?
Guy2: I think it's a science term.
Guy3: Fellas, fellas! Esoteric means delicious!
(back to the real world)
Peter: Lois, "Who's the Boss" is not a food.
Brian: Swing and a miss.

This is Peter's attempt at figuring out the meaning of an unknown word by using context clues. Cruse writes a bit on this subject on pg. 41 of our textbook:
    "...an example of a contextual approach to meaning, because relative normality is a concept which applies only to combinations of elements; that is to say, it implies that meaning is to be studied by observing the interactions between elements and other elements, in larger constructions such as sentences...the normality profile of a linguistic item, that is to say its pattern of normality and abnormality across the full range of possible contexts, gives in some sense a picture of its meaning..."

Neither Peter nor his brain committee are good at judging the normality of  unknown words  or using context clues. But I guess I'm not either b/c I have no idea what esoteric means.
