The word "PEAB" is a rare term that describes a small, brownish-gray seabird found in the Pacific Ocean. The spelling of this word can be explained through its IPA phonetic transcription, which is /piːb/. The "p" sound is pronounced with a puff of air, followed by a long "ee" sound as in "see," then a "b" sound that is pronounced by closing the lips together. While the spelling may seem unusual, the IPA helps us understand its pronunciation with greater clarity.
