The New York Times today has an unusual use of "coincide":


Looking at common-cold coronaviruses, some researchers have predicted that SARS-CoV-2 will become a seasonal winter infection that may well coincide the flu.

It is usual for coincide to be used intransitively, often followed by "with". Here is one example:

Merriam Webster

coincide: intransitive verb
1a: to occupy the same place in space or time
The base of the triangle coincides with one side of the square.
The heroic age of bridge construction coincided with the expansion of the railroads

The NYT quotation is unusual but understandable. Are we therefore to assume a typo (omitting "with"), or does it represent a developing usage?

    One can assume whatever one wishes, toyp or trend. But one data point is not a curve. Apr 16, 2022 at 22:54

    I've found 'These new rules have coincided the continued easing of lockdown that involves reopening shops. ' [RX Live; July 2020; UK]. But decent analyses are based on thousands of data points hereabouts. And not all from medical concerns. Apr 17, 2022 at 16:44

    You might compare "intersect" or "meet" which can be used both transitively and with "with". Of course, English is not very regular.

This is, so far as I can tell, just a typo. Ngram confirms that "coincide the" is extremely rare compared to "coincide with the."
