I have a question regarding usage of "no other". I know no can be used with "singular countable nouns" as well as "plural countable nouns" but I don't know if I can use "no other" in the same way as no.
Here are the examples:
1- This is the only branch of Traders & engineers Pvt Ltd. We have no other branch(es) than this.
2- Peter: Subha, The pen you gave me has broken. Do you have any other pen? Me: No, I have no other pen(s).
My main question is, can I use singular nouns after "no other"? And would you choose "plural nouns" or "singular nouns" in the above examples?
Can anyone who has good knowledge in english answer my question please?
