Required / Hidden Placeholder
Does the language require something even if another language would omit it?
意味
A structural slot that must be filled or understood: dummy subject, copula, article, classifier, expletive, pronoun, or support word.
見分け方
Notice places where your language says nothing but the target language needs a visible item, or the opposite.
例

Same idea, slots differ: English: [It] is raining Zero OK: [∅] raining English: [There] is a book Other: [∅] book exists Check required items: subject, be, article, CL, do
