Samhain is pronounced roughly as "Sow-wn" or "Sow-in," with the first syllable rhyming with “cow” and the second sounding like the short “in” in English. In Irish Gaelic, many guides emphasize a pronunciation closer to "Sow-en" or "Sow-inn," where the final syllable has a light, clipped ending rather than a hard English “man” or “line” sound. Cambridge and other pronunciation resources commonly render the English-adopted forms as /ˈsaʊ.ɪn/ (UK) or /ˈsaʊ.ən/ (US), which correspond to “Sow-in” with a subtle, almost unstressed final vowel in American usage. If you’re aiming for a traditional Irish pronunciation, you’ll often hear it closer to “Sow-inn” with the final n held lightly.
