Sentence examples for on year from inspiring English sources

The phrase "on year" is not a complete sentence and does not make sense on its own
It is grammatically incorrect and should not be used in written English. It is possible that "on year" could be used as part of a larger sentence, such as "I have been working at this company for one year" or "We took a vacation to Europe last year." In these cases, "on year" is a shortened version of "one year" or "last year." Example: "I have been studying French on and off for the past five years."
