Pronunciation & Spelling
The words 'collar' and 'scholar' rhyme with 'dollar' (stressed vowel /ɑː/ followed by /lər/). The words 'polar', 'solar', and 'vulgar' have different vowel sounds (/oʊ/ or /ʌ/), so they do not rhyme, though they share the same ending spelling '-ar'. 'Popular' also ends in '-ar' but has an additional syllable and a /j/ glide, so it does not rhyme either.
