DL's "correct" answer sounds a little off, but I can't explain why. If you want to use "have" then it would sound better as "they have understood it all." But, you don't need the "have." It sounds best as "they understood everything." Is there any reason why DL is inserting "have" into this sentence?
Po-MOemu is essentially a short form of po-moemu MNEniyu, which is "In my opinion". I think Opinion expresses your thoughts, and "According to me" would be more like expressing an assessment that you made.
I thought that "according to me" and "in my opinion" were the same in English.
"According to me" sounds as though you are referencing yourself as an expert on the subject, e.g. "Oh yeah? According to who?" "According to ME." While the same connotation could be applied to "in my opinion," the latter reads more as an assessment, uninformed or informed, and less a declaration of authority.
Which is the worst thing about speaking in a language you don't think the other person understands.
What does "on mine" mean and how standard of a phrase is that in English?
I don't know, bro. I'm a Russian. My internet-traslator translated also 'on mine'
Fair haha. I only ask because you get Australians or Brits on here who say stuff like that and it's acceptable there though not something you'd ever hear in the US.
I would not personally understand if someone said "On mine" in this context (regarding opinions).
