If you wanna say someone put their hand on my shoulder throughout the window should i say extended his hand on my shoulder?
One of many possible sentences I could construct for the scenario described is: He extended his arm, reached through the window, and put his hand on my shoulder. But that just comes down to the definition of extend and what is being expressed. In this case, it’s not the hand that’s extended, but the arm. He extended his hand on my shoulder doesn’t make sense. Not necessarily because of the word extend, but because of the overall sentence. Figuratively, you can extend a hand (to offer help), but not literally.
