Give an example of assonance from the poem Those Winter Sundays?
...by Robert Hayden, a U.S.A poet. You can squirm around it to
find assonance but, as this is a non-rhyming poem, it is
disingenuous to say that 'ached' and 'made' in the first stanza are
examples of assonance, or 'dress' and 'house' in the second, or
'cold' and 'know' in the third. But these are the only vaguely
assonant lines and they appear different points in those stanzas.
So whoever told you that this was a piece of work with good
examples was talking through their assonance.
