Sly smile vs Smirk what are each for you as a native speaker. I'm getting a headache trying to tell them apart using dictionary definitions. thanks!

Do these expressions have the same meaning? "Make a point of doing something" and Have a goal of doing something". Are they similar in meaning? Thanks.

Word Order. I'm never sure when I construct sentences such as these: 1) We want to manage things the best way possible. Or 2) We want to manage things the best possible way. 3) I was able to finish the task in the shortest time imaginable. Or 4) I was able to finish th task in the shortest imaginable time. Don't forget to check for grammatical/spelling errors. Thank you!

Either or Neither? Which one is correct? 1. She will never be either important or famous 2.She will never be neither important nor famous. II suppose the first one is correct because the second one leads to double negative (through the word never) but I want a confirmation. Thanks in advance! :)

What does it mean to get out of one's system?

There used to be. How to turn this into a negative sentence? A) There didn’t use to be B) There didn't used to be C) There not used to be How do you say?

I don't understand this sentence. I'd like an explanation. The sentence is: After the machine has ground the surface of the object down it is polished.  1) Which verb is it in the first part : ground or grind? 2) Could you rewrite the whole sentence in other words so that it is simplified? I can't quite understand the meaning. To me it looks like there is a punctuation mistake but I'm no native speaker so...

It is about the phrasal verb sent away for sth. Sorry if this is a silly question. I just learned that you say you sent away for something when you write and ask for it to be posted to you. In our era we buy so many things online so I was wondering if you can use sent away if you email the company instead of writing an actual letter. If not what are the expressions that mean you ordered a product online. Thanks in advance!
