Tetreault is a French surname that is typically pronounced as "teh-troe". The first syllable "teh" is pronounced with an open "e" sound, similar to "bed". The second syllable "troe" is pronounced with a closed "o" sound, similar to "goat". The final "t" is silent in French, but is often pronounced in English due to the Anglophone tendencies towards word-final consonants. Hence, the spelling of Tetreault is reflective of its French origin and pronunciation.
