There's also "the" vs "the". As in "the boy ate the apple". First 'the' ends with a schwa sound. Second 'the' ends with 'ee' sound.
British English speaker: for me, the two 'e's' have the same sound.
The boy The apple.
Though I do say 'thee end'
My Brother says 'barth', I say 'bath'.
Both schwa for me, native speaker who grew up in Scotland.
