Japanese speakers
Mistake: Pronouncing every letter as "RASUTO IYAA" with an inserted vowel and a fully released t.
Why: Japanese phonotactics require vowels between clusters, and orthography-based learning preserves every letter.
Fix: The t of "last" combines with the y of "year" into a single [tʃ] sound: [ˈlæsˈtʃɪər] or [ˈlæstʃɪər]. The whole phrase compresses. Say "last-chir" — that captures the fusion.
Korean speakers
Mistake: Preserving a clear boundary between the two words, giving "LAS-EU YIA" with released t and separate onset for "year".
Why: Korean orthography maps to sounds and prosody favors clear word boundaries.
Fix: In fast speech, t + y at a word boundary fuses to [tʃ]: [ˈlæstʃɪər]. This is the same rule as "got you" → "gotcha" — the t and the following y merge into a single ch-sound.
Spanish speakers
Mistake: Producing a Spanish-style light [j] for "year" or over-articulating the t of "last" as a full stop.
Why: Spanish [j] does not merge with preceding consonants; each retains its identity.
Fix: Let the t and y coalesce into [tʃ] (like Spanish ⟨ch⟩ but lighter): [ˈlæstʃɪər]. Or in more careful speech, elide the t entirely: [ˈlæsˈjɪər]. Both are natural.
