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

Visual guide
Thought: RAIN Grammar frame: [Subject] + [be] + raining English fills the slot: [It] is raining It = placeholder, not actor
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
Panoramica per lingua

Nella lingua che studi
French often requires structural placeholders such as il, ce, articles, copulas, or support verbs.

Good transfer potential
This block behaves relatively similarly, so you can transfer intuition more safely between the two languages.
