What figurative did Shel Silverstein use in forgotten language?

You're likely thinking of the poem "Forgotten Language" by Shel Silverstein, not a figurative device. The poem itself is a whimsical exploration of the concept of a lost, forgotten language.

While it doesn't use a single, prominent figurative device like metaphor or simile, it does employ some subtle figurative language to enhance its meaning:

* Personification: The poem gives the forgotten language human-like qualities, making it seem alive and capable of "coming back" and "speaking softly" (lines 5 and 8).

* Imagery: The poem uses vivid imagery to describe the forgotten language, comparing it to "a whisper" (line 1) and "a song" (line 4).

* Symbolism: The "forgotten language" can be interpreted as a symbol for anything that is lost or forgotten, such as childhood memories, ancient knowledge, or even forgotten feelings.

The poem's strength lies in its simple yet evocative language, which invites readers to consider the potential of a forgotten language and what it might represent.
