My colleague frequently uses "should" + 3rd person present, e.g. "It should goes ..". Notifying him about that he replied he had a British teacher and this form is correct.
It was surprise to me as I thought the correct form is just the verb base form, e.g. "It should go ..". Asking him if it is correct also for negative sentence, e.g. "He should not smokes." he was not sure..
Could someone confirm it is correct and when it is used in this form?
This question has been closed as off-topic. Why?
I was confronted with a person who mentioned a specific usage in a specific country. I googled it first, found this - it compares frequency of usages of phrases "credit should go to" vs "credit should goes to" as 17900 : 99. There might be 99 occurrences of a bad usage or there might exist some rare context when it is correct.
Does the question suit better to "English Language Learners"? I wouldn't say from the names of the communities but if the StackExchange thinks so, please feel free to move it there. In my opinion, downvoting and closing without explanation just shows disrespect to the urge to understand things..
