Offred is a slave name that describes her function: she is "of Fred" (i.e., she belongs to Fred – presumed to be the name of the Commander – and is considered a concubine). In the novel, Offred says that she is "not" a concubine, but a tool; a "two legged womb". The Handmaids' names say nothing about who the women really are; their only identity is as the Commander's property. "Offred" is also a pun on the word "offered", as in "offered as a sacrifice", and "of red" because the red dress assigned for the handmaids in Gilead.
