Register: formal or technical, finance/tax English. Standard in its technical domain but rare in everyday talk; gloss with a plain synonym when writing for a general audience. A common learner mistake is using the word in a register it does not fit, or assuming a single global meaning; native speakers immediately notice when slang appears in formal contexts, so always check the surrounding register before producing it yourself.
