The Very Model of an Amateur Grammarian

From The Stroppy Editor:

The very model of an amateur grammarian

(With apologies to Gilbert and Sullivan)

I am the very model of an amateur grammarian
I have a little knowledge and I am authoritarian
But I make no apology for being doctrinarian
We must not plummet to the verbal depths of the barbarian

I’d sooner break my heart in two than sunder an infinitive
And I’d disown my closest family within a minute if
They dared to place a preposition at a sentence terminus
Or sully the Queen’s English with neologisms verminous

I know that ‘soon’ and not ‘right now’ is the true sense of ‘presently’
I’m happy to correct you and I do it oh so pleasantly
I’m not a grammar Nazi; I’m just a linguistic Aryan
I am the very model of an amateur grammarian

Go here for the rest of the song. Thanks to Prof. Geoffrey Pullum for the pointer.
