📝 Conjugation Notes
Always attach 「ということだ」 to the plain form (常体 / jōtai) of the preceding word/clause, regardless of whether it is a verb, i-adjective, na-adjective, or noun. Nouns and na-adjectives usually require 「だ」 or 「で」/「で ある」 before 「ということだ」 if stating a fact.
🔊 Pronunciation Tips
In rapid speech, the ‘to iu’ (という) often contracts to ‘t’yuu’ (てゅう) or ‘tte’ (って), especially in informal contexts (e.g., ってことだ). Maintain a neutral tone unless expressing strong surprise or doubt.
🧠 Memory Tips
Think of 「ということだ」 as literally meaning “it is the matter/fact of saying [X]”. This structure forces the preceding idea (X) to be treated as a definitive piece of information or concept.
