English has now become a universal common language used not any longer by the British colonies alone,but including non-commonwealth nations as well.There are some vast pacific islands using English as the national language,either bearing their own names,or or Anglicized names.However there are different types of English spoken by different nations,ethnic groups,and associate states.Each of them have their own unique styles of grammar use.In todays modified,enriched English,it may be confusive to understand each ethnic,or speaking community fashions.So there is no reason to worry,when using your grammar,the way one's wishes,however rules come about during the academic contest,and credibility to distinguish the contrast between the challengers.Of course,there are some occasions,when one can truthfully use superlative terms.e.g.scientific,political,military,and pure grammar vocabularies.Dictionary?..forget about it,or it may mislead.There are many types here,and you are allowed to rate them accordingly to determine whether it's worth your judgement,or not.Use the usual rating scales. 5 = Great
