This essay, which is part three (3) of the report on the formulation of Yorùbá phonology terms from their English counterparts, discusses English phonology terms for letters P, Q, and R and the Yorùbá counterparts, totaling ninety-one (91) terms numbered from 187 to 278.[1] Preceding letters A to O have been discussed in part one and part two of this report, numbers 1 to 104, letters A to G, and numbers 105 to 186, letters H to O, respectively. In this report, we compiled these terms in English, alphabetically arranged, from letter P to letter R, and developed their Yorùbá equivalents. In doing this, we extracted these phonology terms from three phonology textbooks and two specialized/technical dictionaries on linguistics and phonology. We employed the Information Processing Model (IPM) framework. Some of the terms developed are palatalization, ìso̩dàfàjàpè, paragoge ìfìró-bò̩parí, parasitic harmony àǹkóò àfòmó̩, parse ìpínsífó̩rán-ìhun, partial overlapping ìwo̩nú-ara e̩lé̩be̩, phonaestheme fóníìmù-àyo̩túnyo̩, phonemic overlapping ìpòórá fóníìmù, phonological phrase boundary ààlà àpólà fonó̩ló̩jì, phonological prime fó̩nrán-akérépin fonó̩ló̩jì, quantity-sensitive feet è̩wo̩n-atéńté aníwò̩n-agbe̩gé̩, recessive vowel fáwè̩lì àdínkù, redundancy rule òfin aléélè̩
