Consider:
- Please check that the username and password is correct.
- Please check that the username and password are correct.
If I had to break the statement into its parts:
- Please check that the username is correct.
- Please check that the password is correct.
I feel that username and password can be seen as a single noun and therefore the correct form is is. Based on this answer, I'm confused: the number of the verb is determined by the number of the verb's subject. Is username the subject or object?
Can someone please advise?
This question was marked as a duplicate but the duplicate tagged isn't quite related. Rather, based on @user2370114 response, this question is a better match. Furthermore, it doesn't address my concern about the subject vs object distinction (as answered by @RegDwigнt♦).
To summarize:
- If you are speaking of multiple things, and even if both were singular, the copula (verb of being) would still be plural.
- Both
usernameandpasswordare the subject. Interestingly, in my use here,arefelt more natural :)
So can I rather ask: is there ever a time when items can be seen as a single subject and therefore take the singular form of the verb?
that, then I had a list of two items: 'The username and password are correct'. Then this answer indicates thatareis the correct form: http://english.stackexchange.com/a/15770/87168 – Pooven Aug 05 '14 at 10:55
