We know that defining relative clauses can be reduced. Let's look at some examples.
- The boy whom I called yesterday knows you.
= The boy I called yesterday knows you. (The relative pronoun is omitted as it's the object of the clause)
- The boy who is sitting next to you lives in Kolkata.
= The boy sitting next to you lives in Kolkata. (The relative pronoun is the subject of the clause and it's followed by a be verb so we've omitted the relative pronoun and the be verb both)
- The girl who lives in Kolkata is beautiful.
= The girl living in Kolkata is beautiful. ( There is no be verb after the relative pronoun so we change the main verb into its progressive form and then omit the relative pronoun)
- My friend who is a teacher is a good hearted person.
= My teacher friend is a good hearted person.
Now my question is if they are non defining relative clauses , can we omit by ways mentioned above ? Can the following sentences containing non defining clauses reduced?
- Ram,whom I called yesterday, is a very good boy.
- Rima, who is sitting next to you, is very beautiful.
- My mother, who lives in Delhi, is very hardworking.
- My father, who is a doctor, loves me so much.
