1. Loman: The surname "Loman" alludes to the protagonist's declining state and sense of failure. The root "low" suggests his diminishing fortune, status, and self-worth. It also hints at the "low man" on the totem pole, implying his humble position in society and his struggle for recognition and success.
2. Singleman: This surname is particularly symbolic. "Single" can be interpreted in multiple ways:
- Isolation: Willy Loman is essentially a "single man" in the sense that he feels isolated and alone despite being surrounded by family and colleagues.
- Unfulfilled Dreams: Willy's life remains incomplete and unfulfilled. He never achieves his dreams of becoming a successful salesman or providing a secure future for his family. In this sense, he remains a "single" entity, unable to fully develop or reach his potential.
3. Juxtaposition: The contrast between the surnames "Loman" and "Singleman" highlights the dichotomy in Willy's life. He is both a "low man" struggling for success and a "single man" experiencing profound isolation and lack of fulfillment.
4. Irony: The use of the name "Singleman" is also ironic. Willy Loman is far from being a single man in terms of his family life. He is married with two grown sons. However, he leads a life marked by loneliness, alienation, and a haunting sense of being lost and insignificant.
Through the allegorical use of these names, Miller underscores the themes of disillusionment, failure, and the pursuit of the American Dream in Death of a Salesman, adding depth and resonance to the characters and the play's overall message.
