The pronunciation guide uses the ARPABET phonetic system—the same system used in speech recognition and text-to-speech applications.

Vowel Examples:
AE1 = cat, bat
EH1 = bed, head
IY1 = see, me
OW1 = go, boat
UW1 = boot, do
Stress Numbers:
0 = no stress (unstressed)
1 = primary stress (loud)
2 = secondary stress (medium)
Example:
AH0 TH IY1 N AH0
= a-THEE-na (Athena)

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

Quick Definition

A structural design where a poem's sections radiate outward like tree rings, each layer adding chronological or thematic depth, suggesting organic growth and memory.

Detailed Definition
Tree-ring form: Poetic structure organized in concentric layers that accumulate around a central core, analogous to annual growth rings in wood. Each layer represents a complete temporal cycle or developmental stage while remaining permanently visible in the poem's architecture, creating a record of successive phases that readers can trace from center outward.
Example
Example in poetry:
Tree-ring form appears in Annie Dillard’s poetic prose in “Pilgrim at Tinker Creek,” where cyclical observations mimic annual growth; in A.R. Ammons’s “Garbage,” long lines coil like rings around ecological decay; contemporary poet Camille T. Dungy’s “Trophic Cascade” uses concentric stanzas to reflect ecosystem layers; W.S. Merwin’s late poems in “The Shadow of Sirius” use unpunctuated, ring-like repetitions to evoke memory; Indigenous poet Joy Harjo’s “An American Sunrise” structures time as concentric circles of history and return.
Additional Notes
Poetry structured in concentric layers like tree rings, with each ring representing temporal or thematic progression. Related to annual-ring composition.
