1. Each student has his / her own book.

(How do you read "/"? Is it 'or'?)

2. Each student has his own book.
(Do we normally say like this?)

3. Each of the answer is worth 4 points.
4. Each of the answer is 4 points.
(Are both grammatical?)

5. Each of children has a bed.
6. Each of the children has a bed.
7. Each child has a bed.
8. Children each have a bed.
9. Children each has a bed.
10. They each have a bed.
11. They each has a bed.
(Which ones are grammatical among the seven sentences? Thank you for your help. Have a great weekend.)

1.

Yes, the / is usually read "or" but it would be better simply to use "his or her" in the first place. Using the / is just lazy!

2.
Yes, this is one way to do so, but technically it seems to assume that no girls have books! Better phrasing to avoid the whole "his or her" issue is to write the sentence like this: All students have their own books.

3. Each of the answers is worth 4 points.

4. This is not written well.

6, 7, and 10 are correct, although 10 might set the writer up for grammar problems in the next few sentences!

1. In the sentence "Each student has his / her own book," the "/" symbol is typically read as "or." It represents a choice or alternative between two possible options. In this case, it indicates that each student can have either his or her own book.

2. Yes, it is common to say "Each student has his own book" to imply that each individual student possesses their own book. This is often used as a generic pronoun since it is gender-neutral and does not specify the gender of the students.

3. Both sentences, "Each of the answer is worth 4 points" and "Each of the answer is 4 points," are not grammatically correct. The correct phrasing would be "Each of the answers is worth 4 points" or "Each answer is worth 4 points."

4. Only the sentence "Each child has a bed" is grammatically correct. In this case, "each child" refers to every individual child, and "has" is the correct verb form for the third-person singular subject.

5. Both sentences 5 and 6 are grammatically correct, but they have slightly different meanings. "Each of children has a bed" implies that each child individually has a bed (though it could potentially be the same bed shared among them). On the other hand, "Each of the children has a bed" suggests that every child in a specific group or set has his or her own bed.

7. The sentence "Each child has a bed" is grammatically correct and implies that every child, possibly in a larger group, possesses his or her own bed.

8. The sentence "Children each have a bed" is grammatically correct and suggests that all children, as a collective group, have their own beds. The word "each" emphasizes that each child individually has one.

9. The sentence "Children each has a bed" is not grammatically correct. The verb "has" does not agree with the plural subject "Children." It should be "Children each have a bed."

10. The sentence "They each have a bed" is grammatically correct and indicates that each person in a group or set has his or her own bed. The pronoun "they" replaces a group of individuals.

11. The sentence "They each has a bed" is not grammatically correct. The verb "has" does not agree with the plural pronoun "they." It should be "They each have a bed."

I hope this helps clarify the language nuances in these sentences. If you have any more questions, feel free to ask. Have a great weekend!
