The stressed syllable (marked with 1) is pronounced louder and clearer than others.

Quick Definition

The central wedge-shaped stone at the top of an arch. In poetry, it names a crucial element that holds a larger pattern together.

Detailed Definition
The keystone completes an arch by locking its separate stones into a stable whole. Poets can use it to describe a final revelation, a repeated image, a governing metaphor, or a single remembered event that gives coherence to scattered experience. Its position is both central and elevated, allowing it to suggest climax as well as support. A poem may withhold its keystone until the closing lines, where a detail suddenly makes earlier images bear new weight.
Example
Example in poetry:
“Her name was the keystone of the family’s story” identifies one essential element that holds the whole together; A poet might write, “Hope, the keystone, kept the dark arch standing”; In a sequence of stanzas, a repeated image of water can act as the keystone linking separate scenes; “The final forgiveness clicked into place like a keystone” makes reconciliation feel structural and necessary
Additional Notes
The keystone locks an arch into place. In a poem, identify the image, word, or event whose removal would collapse the larger meaning.
