How is figurative language used?

Keats uses both synecdoche and metonymy in the first and
second stanzas. Specifically, however, the metonyms in stanza one are the thatch-eaves,
which represent the people who live in the houses so protected, and the clammy cells of
line 11, which, because they are the location of honey, stand for the honey itself and
the sweetness of the season. In stanza two, synecdoches are hair (line 15), which
figuratively represents the dust of harvested grain and therefore the grain itself;
laden head (line 20), which represents the persons working in the autumnal harvest both
as laborers and as planners of the season; and oozings (line 22), representing
specifically cider but generally the substances made from the year’s produce. These
figures give insights into the intricacy of growth, harvest, and processing, and along
with the personification of autumn, the intention of Nature and life to nurture human
beings.
