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

Lines that mirror each other in length, stress pattern, or syntactic construction

Detailed Definition
Symmetrical lines are poetic lines that mirror each other in length, stress pattern, or syntactic structure, creating visual and auditory balance; this technique reinforces thematic harmony, duality, or the aesthetic principle of formal equilibrium within the stanza or poem.
Example
Example in poetry:
In Alexander Pope’s couplets, “To err is human, to forgive divine” shows symmetrical lines; In Robert Frost’s “Stopping by Woods,” “The woods are lovely, dark and deep, / But I have promises to keep” balances rhythm and syntax; In William Blake’s “The Tyger,” “Tyger Tyger, burning bright, / In the forests of the night” uses symmetrical phrasing; In A.E. Housman’s “To an Athlete Dying Young,” “Smart lad, to slip betimes away / From fields where glory does not stay” mirrors structure.
Additional Notes
Symmetrical lines mirror each other in length, sound, or structure to create balance or reflection; useful for thematic doubling or meditative effect—vary slightly to prevent monotony.
