from The Century Dictionary and Cyclopedia
- n. A petty or pitiful grammarian; one who insists upon the minutest grammatical niceties.
Unfortunately, the loudest grammar snobs are the ones who’ve put the least research into their opinions, and so, for every ten people quietly aware that infinitives can and sometimes should be split, there’s one vocal grammaticaster shouting over them that split infinitives are an abomination in the eyes of Pope.
A cozy gathering of grammaticasters and orthoepists huddled around the Oxford English Dictionary, oblivious to the more worldly pleasures of a coryphee or the opsophagist.
He tells thee true, my noble neophyte; my little grammaticaster, he does: it shall never put thee to thy mathematics, metaphysics, philosophy, and I know not what supposed sufficiencies; if thou canst but have the patience to plod enough, talk, and make a noise enough, be impudent enough and tis enough.
The ‘caster’ in this word comes from the Old Norse ‘kasta,’ to throw.
