Why this pair is hard
Spanish, Italian, French, Mandarin, Korean, Russian and Turkish all have a single high front vowel, so both English words land on it. Hindi, Urdu, Tamil and Arabic have a long and a short i, which helps, but their short one is tenser than the English one, so 'ship' can still arrive as 'sheep'. Japanese separates the two by duration alone, so the short one keeps the tense quality.
