Japanese speakers
Mistake: Pronouncing it as "RUKKU ATTO" with a clear gap and a fully released final t.
Why: Katakana English preserves each word with a supporting vowel and treats each syllable as separate.
Fix: Link the k of "look" directly to the vowel of "at", and the t of "at" flaps if a vowel follows: [ˈlʊkət]. Say "lookat" as one word.
Korean speakers
Mistake: Producing a glottal reset before "at" and full aspirated release on both k and t.
Why: Korean prosody often inserts a light glottal onset before word-initial vowels.
Fix: Let the k slide into the [æ] with no break: [ˈlʊkət]. If a vowel follows in the next phrase, the t becomes a flap: "look at it" = [ˈlʊkəɾɪt].
Spanish speakers
Mistake: Rounding the vowel in "look" toward Spanish [u], giving "LUK AT".
Why: The English [ʊ] vowel doesn't exist in Spanish; the closest is [u], which sounds too long and tense.
Fix: "Look" uses [ʊ] (short, lax, unrounded-ish), not [u:]. It rhymes with "foot" and "good", not with "pool" or "tool". Say [ˈlʊkət].
