Pronunciation

American English

• IPA Pronunciation: /roʊˈteɪʃən/
• Respelling: roh-TAY-shuhn (with "roh" as in "row," "TAY" as in "stay," and "shuhn" resembling the sound in "mission")

British English

• IPA Pronunciation: /rəʊˈteɪʃn/
• Respelling: roh-TAY-shn (similar to American English, with "roh" as in "row," "TAY" as in "stay," and "shn" indicating a slightly more clipped ending than in American English)

In both dialects, "rotation" features a long "o" sound in the first syllable, followed by a stressed "TAY" sound, and ends with a variant of "shn," making the pronunciation consistent across both American and British English with minor variations.

Etymology
