You say /ˌpaɪˈræmɪdl/ in US and UK. The primary stress is on the second syllable: py-RA-mi-dal. Start with a light ‘py’ like ‘pine’ without the n, then a strong ‘RA’ with the mouth open for a clear /æ/ in the second stressed syllable, and finish with a quick /mɪdl/. The emphasis on the second syllable helps maintain the natural rhythm.
Common errors: 1) Misplacing the stress on the first syllable (py-RA-mi-dal should stress the second). 2) Dropping the /r/ in non-rhotic contexts or softening the /d/ into a flap before l (pyramidal). 3) Pronouncing the final -al as an separate syllable /əl/ with too much emphasis. Correction: keep the /æ/ in the stressed /ræ/ clearly distinct, and end with a light, unstressed /dl/ cluster rather than a full vowel.
In US/UK, the main stress remains on the second syllable /ˌpaɪˈræmɪdl/. US tends to preserve the /r/ clearly before the /ɪ/; UK is non-rhotic in some accents but typically still maintains a clear /r/ in this word due to the following vowel, and AU often features a slightly more rounded vowel in /æ/ and a more clipped ending. Vowel qualities may shift: US /æ/ in /ræ/ might be more fronted; UK may have a marginally more centralized /ɪ/ in the penultimate syllable; AU tends toward a lighter /ə/ in the trailing syllables.
The difficulty lies in the multi-syllabic, three-consonant cluster at the end and the secondary stress pattern. The sequence /ˌpaɪ/ (dy/long i) followed by /ˈræ/ requires precise mouth shaping: a high front tongue for /aɪ/, then a low-open /æ/ for /ræ/, and finally a light /dl/ for the end. Learners often misplace stress or pronounce /æ/ as /eɪ/. Practice breaking it into syllables and emphasizing the /ræ/ syllable. IPA awareness helps you map tongue positions.
A distinctive feature is the clear secondary syllable stress on 'ra' and the final consonant cluster /dl/ with a subtle, almost silent /l/ following the /d/. This requires a quick vocal fold closure for /d/ then a soft release into /l/. Mouth shape should avoid turning the final -al into a full vowel; keep it as a light /dl/ sequence. IPA cues: second syllable /ræ/ with primary stress, ending /dl/.

Pyramidal comes from the word pyramid, which derives from the Latin pyramid-, pyramis, from the Greek pyram, ‘wedge, pyramid’; the Greek root is related to pyr, ‘fire’ in some historical accounts but in this architectural sense refers to a pointed, triangular structure rather than combustion. The term acquired the -al suffix in English to form an adjective meaning ‘resembling or pertaining to a pyramid.’ The first known use in English for pyramid (the noun) is medieval, with its earliest attested forms tracing to late Latin and Greek equivalents used in geometric and architectural contexts; pyramidal as an adjective emerged in scientific and mathematical discourse in the 17th–19th centuries, gaining prominence with discussions of shapes, crystallography, and anatomy (e.g., pyramidal cells). The sense has broadened to general descriptions of pyramid-like forms in natural and manufactured structures.
