There are some mistakes which I can understand, and others which I can’t. In class one day this week, the topic was travel, and there were two readings on ‘My worst holiday’. The grammar focus arising from the reading was past simple, because most travel stories are recounted largely that way. The past simple forms appeared in the stories, but the grammar focus activity gave the plain present forms, which the students had to change to the past simple forms, then check them from the story.
One student gave the past simple form of ‘go’ as ‘goesed’, which I don’t/can’t understand how he produced. He has never encountered that form, and there is no rule in English grammar which allows the addition of two different verb inflections, especially when one of them is a present tense form and the other is a past tense form.* Just possibly, he was thinking that she/he/it needs ‘-es’ always, then added ‘-ed’ to make the past tense form, except that the story was told in first person. Just possibly, we would understand the answer ‘I goesed home’ to the question ‘What did you do after class yesterday?’, but would be at least momentarily flummoxed by it.
Another student wrote ‘gone’ as the past simple form. I can understand that. go-went-gone is probably the second hardest verb paradigm for students to remember (behind ‘be’). ‘gone’ is visually and aurally more similar to ‘go’; indeed, ‘went’ began as a completely different word. Certainly, we would understand the answer ‘I gone home’.**
