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 process in which one tectonic plate moves beneath another. It can suggest burial, pressure, and transformation through collision.

Detailed Definition
Subduction occurs when one tectonic plate is forced beneath another and sinks into Earth’s mantle. The process produces deep trenches, earthquakes, volcanoes, and recycled crust, making it rich with poetic implications. A poet may use subduction for feelings or histories pushed beneath the visible surface but still generating heat and upheaval. It suggests that burial is not the same as disappearance; what is driven down may alter shape, gather pressure, and return in unexpected forms.
Example
Example in poetry:
“At subduction’s edge, one plate slipped beneath another,” gives a poem the language of hidden pressure and collision; A poet might compare suppressed anger to subduction: “What I swallowed went under, still burning”; “The ocean floor entered the continent’s dark furnace” poetically describes subduction and its volcanic consequences; In a love poem, “your silence subducted mine” could suggest one voice being forced below another; “Mountains rose from what the earth could not keep buried” connects subduction with uplift, conflict, and consequence
Additional Notes
Subduction occurs where one tectonic plate descends beneath another, producing earthquakes, volcanoes, and mountain building. It offers a strong image for forces hidden below the surface: conflict, burial, compression, and remaking.
