As English has become the most spoken Language in the world, more and more people seek to learn it every day. It has been noted, however, that non-native speakers of English don’t speak it very accurately. There are grammar variations made by them. The most common mistakes are to omit the ‘s’ in the third person singular, to omit the definite and indefinite articles when they are required and put them where standard English does not use them. Some people say that those are not variations, but gross mistakes. Others argue that such mistakes don’t matter, if they are made in spoken English. There is a kind of agreement about the mistakes made in written English. So, the discussion concerns the spoken English. Should non-native Speakers of English worry about those mistakes? Some say that they shouldn’t because the main target in spoken English is to be understood by one another. Others say that non-native English get used to make those mistakes and don’t do anything to speak English accurately. The problem, perhaps, does not concern the feeling of worrying but with the feeling of blame. Non-native Speakers of English should be worried about their English skills, but they shouldn’t blame themselves for their mistakes. They should just try to be consciousness of them and try to correct them so as not make again in the future.
