Pronunciation & Spelling

The target /fɪrst/ has no common rhyming words with the exact /ɪrst/ sequence. Words like thirst /θɜːrst/, burst /bɜːrst/, and worst /wɜːrst/ are spelling lookalikes ending in '-rst' but have the vowel /ɜː/, so they sound different. Fist /fɪst/, wrist /rɪst/, and list /lɪst/ share the /ɪst/ ending but lack the post-vocalic /r/ of first, so they do not rhyme either. These words are useful for comparing how the letter 'r' changes both spelling and sound.
