Pronunciation & Spelling
The words 'elementary', 'complementary', and 'documentary' rhyme with 'supplementary' as they all end with the sound /ˈmɛntəri/. In contrast, 'dictionary', 'necessary', and 'ordinary' have a similar spelling ending '-ary' but are pronounced with /ɛri/ or /əri/, not /ɛntɝi/, so they are not rhymes.
