我的意思是````用英语怎么说

看情况：
如果“我的意思是”是当别人没明白你的意思，用来重复你之前的意思，那就“I mean...”"I wanna say..."之类的，
如果“我的意思是”自己之前说错话了，用来改变之前的意思，那就在句子之前加上“Actually, ..."，如“Actually, I mean...”“Actually, I wanna say...”美国人一天到晚把这个字挂在嘴边。
例子还真不好举，和美国人聊天聊久了，自然而然会蹦出来。
比如你去walmart退货
——问好——

B: oh I'm sorry about that but do you need any help?
A: Em, actually, I wanna my money back.
B: We have to check it.
A: Can't I refund?
B: Yep, I mean you can, but actually we need check it first.
