on the opposite end.. we're always surprised that Americans say.. '' this happened Thursday''.. or where we always so ''ON Thursday''
I think, well from the regions of America I live and was raised, we would say "on" Thursday in answer to a question as in, "When did that happen?" "On Thursday."
Although, eh, now I'm really thinking about it, the answer "Thursday" without the "on" does feel more natural.
It's not that no one here would say, "on Thursday," but (again from my regional experiences) simply, "Thursday" is more common.
I'm thinking of how I would say, "I went to the store on Thursday," but "Thursday, I went to the store." But could just as easily say, "I went to the store, Thursday and saw an armadillo statue I had to have."
This is fun; I love all things linguistic.
Along that line, I love the way my English boyfriend, when talking about dates, will say, "I'm leaving on the Monday and then arrive back on the Friday." It's the
the that is not common to my experience, but sounds so nice and makes sense because he is referring to a specific Monday and Friday.
