Japanese speakers
Mistake: Pronouncing it as "IITO ITTO" with a full t release and separated syllables.
Why: Katakana English preserves each t; the flap-t between vowels is unfamiliar.
Fix: The t of "eat" becomes a flap between the two vowels: [ˈiːɾɪt]. Say "eedit" — one word.
Korean speakers
Mistake: Producing aspirated [tʰ] and clear syllable break.
Why: Korean ㅌ carries aspiration.
Fix: The American flap-t is a short d-like tap: [ˈiːɾɪt]. In British RP, the t may stay as [t] but the linking is still continuous.
Spanish speakers
Mistake: Producing full Spanish [ɾ] tap or preserving both t's.
Why: Spanish [ɾ] is longer than English flap-t.
Fix: Keep the flap very light: [ˈiːɾɪt]. Quick tongue tap, no sustained contact.
