In the sentence
- The partner of an old woman who is residing in the USA will help us
it is clear that the person who will help us is the partner. But, I'm not clear whether the person who is residing in the USA is the partner or the old woman? If I want to convey that it is the woman who is residing in the USA, how do I express this?
On the other hand, if I want to convey it is the partner who is residing in the USA, how do I express this?
Is there any difference between the following?
(a) The partner of an old woman who is resident in the USA will help us and
(b) The partner of an old woman, who is resident in the USA will help us.
Note in the added comma in (b).
