Pronunciation & Spelling
The words 'alchemy', 'albatross', and 'alpine' share the initial 'al-' spelling and /æl/ sound with 'algebra', but they are not rhymes because the stressed vowel and following sounds differ. 'Zebra' and 'cobra' share the final '-bra' spelling and the unstressed /brə/ ending with 'algebra', but again are not full rhymes. Beware of 'bra', which is spelled like the ending of 'algebra' but pronounced /brɑː/.
