IPA: /dɪˈklɛr.ənt/
KK: /dɪˈklɛr ənt/
A person who officially states something, often in a legal context or when applying for citizenship.
The declarant signed the form to confirm their intention to become a citizen.
Declarant → It is formed from "de-" (meaning down or away) and "clarare" (meaning to make clear or to declare). The word refers to someone who makes a statement clear or declares something formally.
Think of someone 'making clear' ('clarare') a statement 'down' or 'away' ('de-') — that's why a declarant is someone who declares.
