I Majored in English and I've been learning it most of my life, but that doesn't mean I'm anywhere near perfect. Sometimes I mess up tenses and verb forms. But I still learn, I look up words and usage and other things as well. I remember even watching a video last year about the correct plural form of the word 'octopus'.
Today I looked up 'no one' and 'any more' which I often used incorrectly in the past. Besides I'm still kind of exploring the topic of my Master's work: which is British vs. American. I decided to use British whenever I write in English which is a little hard since apart from people who are actually from the UK everyone is using the US version and sometimes even the British get confused from too much US version exposure. At least I finally got around to adjusting my Spell-Checks.
