Today I want to help you avoid a very common mistake that lots of people make – and that is writing the word "grammar" like this: G-R-A-M-M-E-R.
There's actually NO "e" in the word grammar; the correct spelling is G-R-A-M-M-A-R.
But when we speak, we pronounce it like "er" – grammer, not gram-MAR – so that's why people often misspell it with -er. It's an understandable error.
There are actually lots of words in English that end with -ar or -or in an unstressed syllable, and we pronounce them more like -ER. Let's practice more of these words.
