The spelling of the word "wirrah" is influenced by its pronunciation. In IPA phonetic transcription, it is written as /wɪrə/, with the stress on the first syllable. The "w" is pronounced as in "water," the "i" as in "it," the "r" as a single flap consonant, and the "a" as in "sofa." This word is not commonly used, but it is derived from an Australian Aboriginal word for a type of fish found in certain rivers.
