Here is a script for the role of Grammarian in Toastmasters that perfectly explains the importance of Grammarian in our meetings. Have a look.

When we are drafting our Toastmaster speeches, or preparing a report, identifying grammatical errors is easy. Often we use MS word to prepare them which does an excellent job of underlining our errors in red giving us an opportunity to correct them. In fact every year, a sizable chunk of Microsoft’s revenue is derived just from its Microsoft Office tools that has amongst other things, MS Word and Power point too.
Looking at the popularity of this feature, soon email service providers like Gmail started providing them too. In fact, right now, an entire website by the name of Grammarly works on just one need – removing errors from our written content. It’s so popular that currently it is valued at more than 1 billion dollars.
Clearly, there are multiple options to identify and correct errors in our typed materials before making them public. But what about the errors we make when speaking.
This is why, every toastmasters has a grammarian. As a Grammarian today, I will keep a track of all the good usage of English, good phrases, words, idioms etc. and more importantly the not so good usage of English and incorrect pronunciations we well.
I am also supposed to give you the word of the day and the word of the day is GULLIBLE. It’s an adjective and it means – easily persuaded to believe something. Examples using the word may be
1) I was quite a gullible kid and believed my father when he said chocolate milk comes from chocolate colored cows.
2) An April fool’s day is a gullible person’s nightmare.
I hope all of you use this word to the maximum. I will keep a score and present my report at the end of the meeting.
