This is a word that I have a hard time remembering. Since I want to double my efforts to improve my grammar and English skills then that means double my efforts. The word has double As, Ms and Rs.
gRaMMaR
Another way to remember this might be a visual image. Usually one might remember their mom or Grandmother (nick name, Gram) being very particular about grammar. So I see the word GRAM (for grandma) in grammar.
If you have some ideas that help you remember the spelling of this word, please feel free to share them. Thanks.
