The poem uses an onion as a metaphor for love. It promises light but its true nature is hidden beneath layers. The speaker offers the onion to her lover, representing her realistic view of love rather than idealized versions. While love can be fierce and possessive, it is also fleeting and potentially "lethal." The various tones convey changing attitudes, from positive to questioning the future of the relationship. The free verse form reflects the chaotic nature of love and life.
