I don't know what it is, but spelling and grammar mistakes seem to be on the rise. It could be the auto-correct in Microsoft Word and Google that's pampering (read spoiling) everyone's language benchmark. It could be just sheer laziness, or too many distractions around us. It could be the falling standards of education. It could be the rise of digital devices. We still don't know the real long-term implications of all this technology around us. If mobile phone waves are killing sparrows, they might be messing with our spelling skills too.
Speaking of mobiles, we can definitely dump some of the blame on the mobile phone and smsing. I love mobile phones and technology. Bt myb thts y we all rite like dis now, evn n collg. Ders no time. I hv frgten de real splings of tings. I also rite in rely shrt sntnces nw. Dis proves we can read ny wrd easly.
But we can't use language like that in printed/published work (not yet at least). Language standards, in India can be surprisingly low in places where they should be high. Pick up the Times of India. On any given day, you can usually find one spelling plus one grammar mistake, and you won't even have to read the entire paper to discover them. Errors are especially rampant in the supplementary paper such as Ahmedabad Times. Surprised? Don't be. Recently, someone pointed out a spelling error in a Penguin book.
English is definitely not the easiest language to master, with more exceptions than rules. The er and the ar are often confused. "I went to collage." (You couldn't have gone to a work of art). Some errors of course result in pretty hilarious situations. Recently we witnessed the 'Osama/Obama is dead' situation. A slip of one letter can mean something drastically different. Imagine the "Diving Mother that helps one in time of need." (Divine became a water sport).
The slips between s and c are countless. Receive and abscess can deceive us all. And you might want to discus something or throw the discuss. Viscous can be vicious to spell. You are pretty likely to find some mistakes in this post, if you read carefully enough.
