Sylvia Plath's (1932 – 1963) poem "Words" is thoughtful. Here are some key  characters of the poem:

Sylvia Plath (Speaker)

The poem is often seen as autobiographical. The speaker reflects the thoughts and emotions of the poet herself. Plath's struggles with mental health and self-expression are knitted into the poem.

"Words"

In the poem, "Words" is personified as a force that can both free and confine. They are seen as both tools and barriers for the speaker. Words can be a source of catharsis and release. Again, they can also trap the speaker in their inner world.
