Pronunciation & Spelling
The listed '-fall' words all end in /fɔːl/ and share the spelling chunk 'fall', but 'outfall' has primary stress on the first syllable (/ˈaʊtfɔːl/), so they are not perfect rhymes. Be careful with 'fallout' (/ˈfɔːlaʊt/): it reverses the 'out' and 'fall' chunks and sounds different.
