Why this pair is hard
Spanish has no word-final m, so 'sum' ends like 'sun'. French and Portuguese nasalise the vowel instead of closing the lips or touching the ridge, so both endings can disappear. Japanese has one syllable-final nasal that takes its shape from the next sound, so a final M can drift toward N.
