FCM

 I wrote absense instead of  absence . I lost some sense (pun intended) to write the wrong spelling. 

 While writing "accommodate", I typed accomodate and wondered why there was a red underline. Got confused while thinking about the correct spelling. Then used the spelling suggestion to realize that there are two Cs and two Ms in accommodate.

 Today, while working on a workout on the  Elevate app, I came across a word and I spelled it as Yatch. And it was wrong, obviously. I might have learned the correct spelling of Yacht when I was a kid. But over the years, I had remembered it as Yatch.  I guess it happened because I did not knew the correct pronunciation of the word. Instead of pronouncing it as  jɒt , I had alway pronounced it as  j atʃ , similar to 'match'.

Recently while writing violate , I typed violet . Because these words are similar and I type very fast, I often end up typing violet even when I am trying to type violate . Violet is a colour while violate means break or fail to comply with (a rule or formal agreement), treat (something sacred) with irreverence or disrespect or rape or sexually assault (someone).

Since few days I am noticing that I am constantly typing customise as costumise . Why the O and U are swapping their places while I am writing. I hope that I will get rid of this Frequently Committed Mistake (FCM).

Litre/liter and Litter sounds so similar. But today I typed litter, when I wanted to type liter. Then I realised that I made some mistake and rectified it. Litter means trash, while liter/litre is a metric unit of capacity.
