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.

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 tua lingua madre
Italian normally does not need dummy subjects, but articles and support forms may be required elsewhere.

It rains.
Nella tua lingua di studio
L'inglese richiede spesso un soggetto e parole-segnaposto come it e there, anche quando da sole significano poco.
It is raining.
it = segnaposto obbligatorio come soggetto, anche senza un vero significato
Chi studia può omettere i soggetti segnaposto o fraintendere strutture come there is e it is.
