How to Pronounce Rhesus Macaques
"The rhesus macaques at the primate center were vaccinated in a routine health program."
"Researchers chose rhesus macaques for the study due to their genetic similarity to humans."
"A new colony of rhesus macaques arrived at the facility for long-term observation."
Say REE-zus MA-kakz (US) or REE-zuhs MAH-kahkz (UK). Stress the first syllable of each word, with a light, quick rhotic vowel in the first ‘Rhesus’ and a clear, explosive rend of ‘macaques’ ending. IPA: US /ˈriː.zəs məˈkæks/; UK /ˈriː.zəs məˈkɑːk.ɪz/; AU /ˈriː.zəs məˈkæɪkɪz/. Visualize: “REE-zəs MAH-kacks.” Mouth positions: start with a rounded back vowel in the first syllable, then a reduced schwa, and a sharp velar stop for the second word’s final consonant cluster. Audio reference: consult a reputable phonetics resource or Pronounce; listen to native primatology lectures to hear the term in context.
Common errors: misplacing stress (giving equal weight to both words), pronouncing ‘Rhesus’ with a lax ‘i’ instead of /iː/, and conflating ‘macaques’ with ‘macs’ or mispronouncing the final -ques as -kez. Correction: emphasize /ˈriː.zəs/ for Rhesus with a long E, then use /mə-ˈkæks/ or /mə-ˈkaːks/ for macaques, ensuring the final -ques is pronounced as /kɪz/ or /kæks/ depending on region. Practice slow, then speed, to lock the final nasal or stop consonant accurately.
US tends to /ˈriː.zəs məˈkæks/ with a rhotic /ɹ/ and a clipped /z/ in rhesus; UK uses /ˈriː.zəs məˈkɑːkɪz/ with broader vowel in macaques and non-rhotic Rhesus; Australian often smooths vowel sounds and may emphasize the second word slightly differently: /ˈriː.zəs məˈkæɪkɪz/ or /ˈriː.zəs məˈkæːkɪz/. In practice, length and vowel quality shift subtly by accent, but the first word remains stressed and the second is secondary to primary phrase intonation.
Because the two-word proper noun contains back-to-front vowel contrasts and a potentially unfamiliar final consonant cluster in macaques. The first word insists on a long /iː/ and a reduced second syllable, while the second word ends with a voiced alveolar stop plus a final /s/ that many speakers mispronounce as /z/ or drop entirely. Practicing the transition between /z/ and /k/ clusters and focusing on mouth shape around /æ/ vs /ɑː/ helps clarity.
Do you stress the first syllable of Rhesus while keeping the macaques’ vowel sound distinct? Yes. The first word carries primary stress on the first syllable (ˈriː.zəs), the second word carries primary stress on the first syllable of macaques (məˈkæks or məˈkɑːkɪz), depending on accent. This two-word phrase requires deliberate contrast between the long /iː/ in rhesus and the short/central vowel in macaques, plus careful enunciation of the final consonants to prevent a generic ‘monkey’ mispronunciation.

The term rhesus macaque derives from the genus Macaca, a Latinized form of a Tupi- or Malay-derived word historically used by early naturalists to classify macaques. The species name mulatta traces to Latin mulatta ‘red-haired’ or ‘reddish,’ a reference to coloration observed in some populations. The combined common name ‘rhesus macaque’ entered scientific and popular usage in the 18th–19th centuries as European naturalists cataloged Asian Old World monkeys. The word ‘rhesus’ itself likely crystallized from older transliterations of regional names or descriptions used by travelers and traders in South Asia, the broader macaque lineage being among the earliest documented primates in taxonomy. In modern usage, “Rhesus macaque” is treated as a standard proper noun in biology, veterinary medicine, and ethology, with “rhesus” sometimes further capitalized when referring to strain-specific lines in research contexts. The term is widely recognized in global scientific literature and standard dictionaries after the advent of standardized taxonomic naming conventions in the 19th century and persists in contemporary primatology and biomedical discourse as a fixed species epithet paired with the common noun ‘macaque’ for clarity and specificity.
