Question

1-can we use "No" with a single countable word? as in: "a girl with no name".

2-which one is correct? "less people" or "few people"

3-"put your shoes off please" - is "putt off" the correct word here?

4-"much too confusing" - is this normal to use "much too"?

Answer 1

1. yes
2. it depends on the sentence and if its past or present e.g. there were less people or theres only a few people
3. i would say take your shoes off please! put does not makes sense in this case, however you would say put your shoes on please!
4. in some situations i suppose but i would usualy say too confusing without the much e.g. this work is too confusing

Hope this helps
