The spelling of "wert service of" can be confusing for English learners because of its unusual combination of letters. However, the phonetic transcription reveals its pronunciation as /wɜːrt/ /ˈsɜːvɪs/ /əv/. The first syllable "wert" is pronounced with the vowel sound /ɜː/, which is like the "ir" sound in "bird". The second syllable "service" has the stressed vowel /ɜː/ as well, followed by the "v" sound and the silent "e". Finally, the preposition "of" is pronounced with the short vowel sound /ə/, like the "a" in "sofa".
