You say /poʊst mɛrɪdiˌɛm/ in US and UK as /pəʊst mɜːrɪdiːɛm/ with slight variation. Primary stress on the first syllable of both words: POST, MERI- diem. Lip rounding is minimal; the /oʊ/ is a close-mid diphthong, /ɛ/ is open-mid front, and /iː/ or /iːɛm/ ends; keep the 'mer' syllable crisp and the final '-iem' as a long /iː/ or /iɛm/ depending on accent. Audio references can be found on pronunciation platforms or dictionary entries for p.m. style usage.
Common errors: misplacing stress (saying ‘POST-merz-idiem’), pronouncing ‘mer’ as ‘murr’ or overemphasizing the final -diem. Corrections: keep primary stress on POST, then MER- as a clear syllable, and treat -idiem as a light, two-syllable tail /ˈiː.diːˌɛm/ or /ˌiːˈdiːɛm/ with a steady tempo. Ensure the /oʊ/ glide is accurate, and don’t reduce ‘mer’ into a single schwa; keep it as two distinct phonemes /mɛr/ or /mɜːr/ depending on accent.
In US: /poʊst mɛrɪˈdiːɛm/ with rhotic r and clear /ɪ/ in mer- and a longer final /iː/. UK: /pəʊst mɜːrɪdiːɛm/ with non-rhoticity influences, shorter /ɜː/ quality, and perhaps a lighter final /iːɛm/. AU: /poːst mɜːriːdiːɛm/ featuring broader vowel in /poːst/ and similar non-rhotic /ɜː/ in meridiem; final vowels can have a longer/diphthongal ending in some speakers. Overall, vowel quality and rhoticity differ; the core syllables remain recognizable.
Difficulties come from the two-syllable Latin construction with a relatively uncommon English prosody: the second word begins with a rhotic /m/, but the spine of the word includes a subtle /ˈmerɪdiɛm/ where the final two vowels create a longer cluster. The sequence /merɪdiˌɛm/ can be tricky due to rapid transition between syllables and the diphthong /oʊ/ in the first word. Additionally, the full phrase is relatively formal and less familiar to many speakers, increasing tendency to mis-stress or compress sounds.
A notable feature is the explicit two-word boundary with primary stress on POST, followed by MERI- with secondary stress on the onset of the second word. There are no silent letters in standard pronunciations; the challenge lies in maintaining clear /t/ release from /poʊst/ and the distinct articulation of /mɛrɪdiɛm/ without eliding vowels. In some rapid speech, speakers may reduce the second word slightly, but careful enunciation preserves the multi-syllabic rhythm.

Post meridiem derives from Latin: post meridiem, meaning after midday. Meridies means noon or midday; post- signals after. The phrase originated in classical Latin as a way to distinguish times after solar noon. In Latin, post means after, and meridies derives from the sun’s meridian crossing. The borrowing into English retained the two-word capitalized form often used in technical writing; over time, ante meridiem and post meridiem were used to denote times relative to noon, particularly in schedules and medical/clerical contexts. The first known uses in English date to the late 16th to 17th centuries, with increasing standardization in nautical, railway, and legal documents by the 19th and 20th centuries. In modern usage, the term appears most often in formal or legal contexts, and is sometimes abbreviated as “P.M.” or “p.m.” in running text. The Latin origin is retained, but in English it is treated as compound time designation rather than a direct translation.
