Stressed on the second syllable: pi-RA-ru-ci (US: /ˌpɪˈrɑːˌruː.ki/; UK: /ˌpɪˈrɑːˌruː.ki/). Break it into four syllables: pi-RA-ru-ci with a light, quick final consonant. IPA guidance: US: /ˌpɪˈrɑːˌruː.ki/; UK: /ˌpɪˈrɑːˌruː.ki/; AU: /ˌpɪˈrɑːˌruː.ki/. Aim for a clean /r/ and avoid a vowel reduction in the first syllable. You’ll hear it as pi-RA-ru-ci, with the second syllable carrying the primary stress.
Two common errors: (1) Misplacing stress (giving equal weight to all syllables). Correct by emphasizing -RA- in the second syllable: pi-RA-ru-ci. (2) Slurring final -cu to -ku or -ci as a syllabic cluster. Keep final -ci as a soft, separate syllable with the /i/ sound clearly distinct. Practice with slow tempo, then speed up. A practical cue is to say Pi-RA-RU-ki with a short, crisp final 'ki'.
In US and UK, the vowel in the second syllable tends to be a broad [ɑː], keeping a clear /r/; the final -ci is /ki/ rather than /si/. Australian speakers typically keep rhoticity intact in similar positions, with a slightly flatter vowel in the middle syllable and clearer final /ki/. All share four syllables, but vowel length and rhotic quality can shift slightly: US/UK lean toward taller, tenser vowels; AU may be a touch more centralized.
The difficulty often comes from the unusual four-syllable sequence and the mid-to-back vowel in the second syllable. The /r/ in -ra- sits between a r-colored approximant and a trilled variant depending on speaker; the final -ci requires a crisp voiceless /k/ before a final /i/. Practicing with slow articulation and explicit IPA cues helps acquire stable stress and segment timing.
A unique element is the combination of a back, tense vowel in -RA- and a high front vowel in -ci. The second syllable carries primary stress, so you’ll want to open the mouth wide for /ɑː/ or similar; keep the /r/ fairly strong but not rolled; and finish with a precise /ki/ without devoicing. IPA anchors: US /ˌpɪˈrɑːˌruː.ki/; UK identical; AU /ˌpɪˈrɑːˌruː.ki/.

Pirarucu derives from Portuguese, a loan from indigenous languages of the Amazon region, reflecting the fish’s prominence in local culture. The most widely used name, pirarucu, is often used in Brazilian Portuguese; arapaima is the name in English-language contexts and in parts of Brazilian and Peruvian trade, where the fish is known as arapaima gigas scientifically. The etymology traces to Tupi-Guarani roots, with pirá meaning fish and rûcu or rua referring to large or impressive. Early European traders encountered the fish in the Orinoco-Amazon basin during the colonial era, and the term solidified in mid- to late-19th century zoological literature, expanding into modern multilingual reference to this iconic Amazonian species.
