Required / Hidden Placeholder
Does the language require something even if another language would omit it?
Znaczenie
A structural slot that must be filled or understood: dummy subject, copula, article, classifier, expletive, pronoun, or support word.
Jak to rozpoznać

Widok językowy
W języku ojczystym
Polish uses to and jest in structural slots, but weather and impersonal clauses differ.
To jest ważne.
This is important.
W języku docelowym
French often requires structural placeholders such as il, ce, articles, copulas, or support verbs.
Il pleut.
It rains.
Learners may omit dummy il or choose ce/il incorrectly.
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
