I have a question about the usage of "adopt":
Grumman's F9F Panther was adopted by the U.S. Navy as their primary jet fighter in the Korean War period, and it was one of the first jet fighters to employ an afterburner.
Some FYE Instructors and other course instructors adopt the book for their course for the semester. It is not an expectation of FYE instructors to adopt the book as part of the class.
I checked a dictionary, which has this definition for "adopt":
def 2a: to begin to use or have (a different manner, method, etc.)
which suggests that one can adopt a method, but has no mention of adopting a fighter jet or adopting a book.
So, are the examples wrong? Could it be that the authors of the articles meant to write "adapt" (meaning "modify"), but accidentally used "adopt"?
