noun
allusion
uh-LOO-zhuhn/əˈluːʒn/
An indirect reference to someone or something.
The reader recognizes an allusion to the Trojan horse in the modern book.

Etymology
The “play” root underlies a Latin noun meaning “a playing with” or “a reference to.” Earlier English senses included metaphor and wordplay; the modern sense keeps the reference indirect rather than spelling it out.
In context
"What's the glass like to-night, Thalassa?" remarked Robert Turold absently. The allusion was to a weather glass which hung in the hall downstairs.
