What literary devices does Atwood use to explore the position of women in 'The Handmaid's Tale'?

A recurring device in The Handmaid's Tale that Atwood uses to demonstrate the inferior position of women in Gilead is the use of names. Offred is the protagonist of The Handmaid's Tale and her name is symbolic of her subjugation to her Commander, Fred. The two syllables of the name "Offred" can be divided into the preposition 'of' and the name of her Commander, Fred, thus implying Offred's subordination as a woman in Gilead. The onomatopoeia of "Offred" suggests being of the colour red, thereby emphasising the specific restricted position of handmaids in Gilead, who are categorised by the red garments they are forced to wear and therefore limited from social mobility.
