I am trying to write a sentence like the following:

The skills I acquired is/are knowledge in A, B, and C.

However, I know that uncountable nouns such as knowledge doesn't go with are. Yet, the subject is a plural noun skills so are seems to be appropriate. Which one is correct?

  • You have to use "are". Mismatches in number are not uncommon, cf. These results were really something to be proud of.

1 Answer 1


The sentence you quoted is a shortened version of this: "The skills I acquired are knowledge in A, knowledge in B, and knowledge in C." The second and third occurrences of "knowledge in" may be omitted, but the things acquired are still multiple.
