Two words to make you look even more swotty:
Semantics "The Study of Word Meanings"
e.g. 'in the slogan "cats like felix, like felix" the author's plays on the semantic similarity in "like"'
Lexis "another term for vocabulary", or simply as substitute for "words".
e.g. "The author's choice of lexis particuarlly emphasises the severity of Mr Jones' Carrot stabing incident".

Just two words I learnt in English Language. It's almost like 25% of the course is learning intelligent sounding words.. sorry "lexis" to replace all your old ones.

And a "new word" is a "neologism"
