Practical English Usage lists over a hundred common mistakes in the English language. Even very advanced students of English can make mistakes – nobody’s perfect! Swan (2005) has listed a number of them.
“Will you go and see me when I’m in hospital?” = Will you come and see me when I’m in hospital?
(134.4) We use come for movements to the place where the speaker or hearer is. We use go for movements to other places.
“May you go camping this summer?” = Do you think you’ll go camping this summer?
(339.3) May is not normally used to ask about the chance of something happening, except in indirect questions.
“My cousin works for the NATO.” = My cousin works for NATO.
(2.3) Articles are usually dropped before acronyms.
“My wife will be angry unless I’m home by 7:00.” = My wife will be angry if I’m not home.
(601.2) Unless means ‘except if’. Unless is not used when the meaning is more like ‘because … not’.
“We were poured water on.” = We had water poured on us. / Water was poured on us.
(416.2) If there is already a direct object, the second object (after the preposition) cannot become a passive subject.
