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 fine-grained sedimentary rock that splits into thin layers. It suggests compression, silence, and pages of buried time.

Detailed Definition
Shale is a sedimentary rock formed from compacted mud, clay, and fine silt, often laid down in quiet water. Its thin layers can split like pages, preserving subtle traces of ancient environments and, sometimes, fossils. Poets may find in shale an image of compressed speech or history stored in silence. It suggests that soft material, given enough pressure and time, can become a record: fragile in layers, yet enduring enough to outlast the world that formed it.
Example
Example in poetry:
The shale split into thin pages, each layer preserving a different age of mud; A poet may compare shale to a book because it breaks along flat planes like brittle pages; Rain darkened the shale path, and the speaker read the hillside’s weathered history; In an environmental poem, shale can evoke buried time, fossil traces, and the pressure of deep earth
Additional Notes
Shale develops from compressed mud and often preserves fossils. Because it cleaves into sheets, it can resemble sealed pages, records, or quiet histories.
