This is great!
A question -- shouldn't "from" be removed from this sentence?
We must choose from among A, B, or C.
Sozobe, The from
is correct. The among
suggests a group. Something must be selected from the group. You could also say, We must choose A, B, or C. Three individual things as opposed to a group of things. Once the among
is added, the from
must be added as well. I hope my explanation is clear.
Walter and Steissd, If English isn't taught as a mandatory subject in school, people must learn it on their own, which is not always easy or even possible.
I tutor ESL students. Some learned English in school, and others didn't. What I've learned from this is that becoming fluent in English, or any language, as an adult is a daunting and difficult task. I don't think I could do it.
