いった is derived from the verb 言う (いう – to say/call) in its past tense form. It acts as a set phrase here. It directly follows nouns or phrases that act as nouns.
🔊 Pronunciation Tips
The “i” in いった is a short “i” sound, and the double “t” indicates a sokuon (っ), which causes a brief pause before the “ta” sound.
