Question: Given that this sentence is in the hypothetical/conditional form (the -us in "ŝatus"), does that mean that the speaker is approximately saying "if it were not raining, then I would want to go outside"?
In other words, is "Pluvas" the "conditional" in this sentence? And if so, is this normal, and is this acceptable in Esperanto to have the conditional already determined/decided? Is this frowned upon?
Just like in English, they mean different things. The first focuses on you being happy with buying the apple (if..... something), the second with buying the apple.
Watch out for the -us, too. It's very wishy-washy. The reason it's used in the Duo sentence is because "pluvas" implies "mi ne povas eliri."
