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

The edge formed where two vaults intersect. In poetry, it describes a seam where separate formal or thematic movements meet and strengthen each other.

Detailed Definition
A groin is the angled ridge created by the intersection of two barrel vaults, concentrating structural force along a visible seam. In poetry, a groin can describe the meeting point of two patterns: public and private language, narrative and lyric movement, or two conflicting images. Rather than smoothing the junction away, the poem lets it become a source of strength and definition. The term emphasizes productive intersection, where separate arches combine to support a larger space.
Example
Example in poetry:
“Light pooled in the groin of the vault” uses groin for the crossing ridge where two barrel vaults intersect; A poet can write “pigeons circled the groins of the cathedral” to show the complexity of vaulted space; “Each groin gathered shadow into a stone X” turns an architectural junction into a visual pattern; “Under the groined ceiling, their voices crossed and vanished” connects intersecting vaults with intersecting human speech
Additional Notes
A groin is a reinforced intersection, so in poetry it names the productive meeting of two patterns, such as two voices, meters, images, or themes. The seam should feel structurally important.
