Non-native speakers find it difficult to speak just what they really want; sometimes they even struggle to obtain basic information concerning products or services while communicating.
Teachers frequently complain about non-native speakers' lack of critical thinking. Sometimes they feel that students are lost or confused but the problem lies in the student’s ability (or rather inability) to communicate effectively.
Different speakers have different motives behind learning English − some learn it to clear their examination papers, while some to get job offers, and there are some who learn English simply because they love the language.
It's still debatable if motivation yields success or it's the other way round, but English can only be learnt out of the love to be able to hold a meaningful conversation in it.
People interested in improving their Spoken English need to understand that learning the rules and usages of English Grammar does not improve their chances of speaking the language, but confuses them and discourages their speaking.
Spoken English can be only enhanced by repeated listening to correct usage, constantly speaking the language with audiences with different levels of aptitudes in speech, and learning grammar rules and usages simultaneously.
