2 syllables: Di, ploid. Stress on Di.
DEYE-ployd
/ˈdaɪ.plɔɪd/
Diploid is pronounced DEYE-ployd (/ˈdaɪ.plɔɪd/). It has two syllables (Di-ploid), with the stress on "Di". Diploid is a biological term describing a cell or organism that contains two complete sets of chromosomes, typically one inherited from each parent. It contrasts with haploid cells, which carry a single set. Diploid organisms have paired homologous chromosomes, enabling genetic recombination and stable trait inheritance. In genetics, “diploid” is used as a foundational descriptor of most somatic cells in animals and plants.

How to Pronounce Diploid
"In humans, somatic cells are diploid, containing two copies of each chromosome."
"The diploid number in this species is 2n = 46."
"During meiosis, diploid cells give rise to haploid gametes."
Diploid is pronounced dy-PLOYD, with the primary stress on the second syllable. IPA: US/UK/AU: /ˈdaɪ.plɔɪd/ or /ˈdaɪˌploɪd/ depending on emphasis. You’ll start with /ˈdaɪ/ (like die) and move into /plɔɪd/ (like ployd). The /ɔɪ/ is a rounded diphthong; keep it a single, smooth glide into /d/. Audio can be found on pronunciation resources for a model reference.
Common mistakes: 1) Slurring the /ˈdaɪ/ into /daɪɪ/ or misplacing stress as /daɪˈploʊid/. 2) Tripping on /ɔɪ/ or pronouncing it as /oi/ in 2-syllable variants. Correction: pronounce /ɔɪ/ as a single, elongated diphthong with a gentle lip rounding, keep primary stress on the second syllable, and ensure syllable boundary is clear: /ˈdaɪ.plɔɪd/.
In US and UK, primary stress on the second syllable with /ˈdaɪ.plɔɪd/. US speakers may slightly reduce the /l/ in rapid speech; UK speakers may lengthen the /ɔɪ/ and keep a crisper /d/. Australian speakers often maintain the same segmental sequence but with a broader vowel quality in /ɔɪ/ and a more pronounced /d/ at the end. Overall rhoticity has little impact here since /r/ isn’t involved.
Diploid challenges include the /ˈdaɪ/ onset, a tight boundary between /daɪ/ and /plɔɪd/, and the /ɔɪ/ diphthong’s rounded, mid-to-high glide. Speakers often blend /d/ into the following consonant or misarticulate /ɔɪ/ as /oɪ/. Focusing on a clean break: /ˈdaɪ/ + /plɔɪd/ helps maintain correct syllable rhythm and prevents a clipped or mis-timed glide.
The word uniquely combines a stressed syllable with a three-consonant onset cluster /pl-/ and the /ɔɪ/ glide, requiring precise tongue placement: start with a high front vowel /aɪ/, then move to an open-mid back rounded /ɔɪ/. The tip of the tongue should release into a light /l/ before the /d/. This sequence—/ˈdaɪ/ - /plɔɪd/—is distinctive and worth deliberate practice.

Diploid comes from the Greek di- meaning twice or double and -ploidos, from ploid, meaning fold or chromosome set (via Latin diploide, from Greek diploeidēs). The term was adopted in genetics to describe cells that carry two complete sets of chromosomes, replacing earlier descriptions of paired chromosomes. First used in the 20th century as cytogenetics matured, diploid contrasted with haploid (single set) and polyploid (more than two sets). The word’s core meaning—two complete chromosome sets—remains stable as cytology and molecular genetics advanced, but its usage broadened from strictly cell biology to organismal genetics, evolutionary biology, and crop science. Today it appears in discussions of genome duplication, speciation, and breeding, with the 2n convention widely used to denote diploid chromosome counts in species descriptions.
