- Raman’s marriage with Sita is unbreakable.
- Raman’s marriage to Sita is unbreakable.
Which one is correct?
Marriage ‘to’ is more acceptable. We say Raman is married to Sita (Sita is married to Raman). But there is a very common tendency here to use ‘with’, which is not readily digested by our grammarians. Personally, I also would prefer ‘to’.
In standard modern British English it should be “marriage to (someone)” and “married to (someone)”. However, I believe that “marriage with (someone)” may have been more common in the past. “married with (someone)” is impossible to my ear.
