Like recently where I am, it’s pushing “anticuado” as “outdated”. Except that is obviously “Antiquated”. Don’t rely on word similarity without checking dictionaries, otherwise you will end up like people who think “bizarro” means “bizarre”. False friends are a thing. “obliguado” doesn’t seem like a real Spanish word to me, and the RAE dictionaries seem to agree with me. Also it’s very common for certain words to have no equivalent translation with the same root, so you will have to settle for “words used in the target language in this situation” even if they don’t quite get the nuances across.
