Figure of Speech
Zeugma
From Greek zeugma: a yoking. Syllepsis is the type where the word is grammatically correct but semantically mismatched. Pope's use is simultaneously a pun and a social satire.
Definition
A single verb or adjective that governs or modifies two or more nouns in grammatically or semantically incongruous ways.
Example
Pope: 'She sometimes counsel takes, and sometimes tea' — 'takes' governs both 'counsel' and 'tea' absurdly.
