语境与语域Context & Register
[object Object]
发音与拼写Pronunciation & Spelling
Words like 'found', 'round', and 'sound' share the 'ound' spelling and the same vowel /aʊ/ as the first syllable of 'boundary', but they are one syllable while 'boundary' is three, so they are not perfect rhymes. Words ending in '-ary' (e.g., 'dictionary', 'library', 'secretary') share the spelling but are pronounced with /ɛri/ at the end, whereas 'boundary' ends with /dɝi/ (the 'd' is part of the stem). Be careful not to confuse the pronunciation.
