GOTEL

Acronym for Guardian of the English Language. A person dedicated to proper spelling, punctuation, grammar, and usage. A GOTEL will sometimes, on a discussion thread, leave a polite comment that corrects an error. A courteous GOTEL will avoid correcting a speaker in live conversation, but may gently hint at correct usage by employing the word or term properly. GOTELs are frequently found among the ranks of editors, teachers, and word-game enthusiasts.

As a dedicated GOTEL, I pointed out that the term 'just desserts' should properly be written 'just deserts,' as it refers to something justly deserved, not a slice of cheesecake which might be chosen for dessert after a meal.
