Final answer:
Allusions in 'The Waste Land' by T.S. Eliot contribute to its meaning by connecting it to other literary works, events, and figures.
Step-by-step explanation:
An allusion is an indirect or implied reference. In the case of 'The Waste Land' by T.S. Eliot, the allusions used throughout the poem contribute to its overall meaning by connecting it to other literary works, cultural events, and historical figures. For example, the reference to the biblical story of the Fisher King in the poem helps to convey themes of fertility, redemption, and the loss of spiritual direction. By using allusions, Eliot adds layers of meaning and invites readers to make connections between different texts and ideas.
