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 proportion of content-rich words (nouns, verbs, adjectives) to grammatical function words in a poetic line or text.

Detailed Definition
Lexical density refers to the ratio of content words (nouns, verbs, adjectives) to function words (prepositions, articles) in a poem, indicating its conceptual richness and syntactic complexity; high lexical density (as in Donne or Hopkins) conveys intellectual intensity and imagistic compression, while low density (as in nursery rhymes) favors rhythm and accessibility, making it a key metric for analyzing poetic style and cognitive load.
Example
Example in poetry:
Shakespeare’s sonnets show high lexical density: “When I do count the clock that tells the time”; Scientific poetry uses dense terminology: “mitochondria, synapse, dendrite”; In contrast, nursery rhymes have low lexical density; Dickinson achieves density through compression: “My life closed twice before its close”; Contemporary dense verse: “Quantum foam births stars in silent syntax”
Additional Notes
Ratio of unique words to total words; measures vocabulary richness. High density suggests complex, compact meaning. Related to diction and semantic texture. Study tip: Calculate for different poets to compare styles quantitatively.
