Thank you for your help. Could you tell me fs it the first sentence utterly wrong or it just has a different meaning? if that is the case, what does it mean?
(e.g. basic sentences like: John is my father, Mariam is my mother are sentences about my family? Or in this case can I use on as well?) Twice thanks!
Like many, many, many sentences that students bring here, its grammar cannot be faulted, it is just not as usual. You asked which was 'better', and I have indicated what I think is the standard utterance.
