What fantastic reasoning! I am constantly amazed at the early and current astronomers, able to work out fairly and increasingly accurate cosmological views from pinpoints of light.
'I will borrow you that book' means I will lend it to you, just to give an example of a word changing to its opposite meaning.
Anecdotally, today in Germany, it’s really tricky for Germans with a very strong grasp of English to distinguish between ‘borrow’ and ‘lend’.
One I've noticed that is US vs UK/NZ/AU/...: "bring him with you" vs "take him with you", which has a directional component in British usage that I can't quite explain (away from the speaker maybe?) that the Americans don't do.
I’m Australian (NZ-adjacent) and have no idea what that means.
