How to copy part of a text, iOS10 In iOS 10 Apple added the ability to react to messages (“tapback”). You can give a thumbs up, a heart, laughter, etc. You do so by tapping and holding the message and then tapping your reaction when the options pop up.

Before iOS 10, though, tapping and holding a message allowed you to select part of the message, just like tapping and holding text most anywhere else on the iPhone.

Is it still possible to partially copy text from an iMessage or SMS? If yes, how do we do so?
Best way is to select "forward" then you can select part of the message to copy. Apple should fix this though.
