"Lighter-than-air" functions primarily as an adjective, describing something having a low density. The syllabification and stress remain consistent regardless of its use in a sentence.

8. Definition & Semantics:

• Definition: Having a density less than that of air; buoyant.
• Grammatical Category: Adjective
• Synonyms: buoyant, weightless, airy
• Antonyms: heavy, dense
• Examples: "The balloon was lighter-than-air and floated effortlessly." "Lighter-than-air craft, such as airships, were once common."

9. Phonological Comparison:

• lighter: light-er (/ˈlaɪtə/) - Similar syllable structure, comparative suffix.
• higher: high-er (/ˈhaɪə/) - Similar syllable structure, comparative suffix.
• wider: wide-er (/ˈwaɪdə/) - Similar syllable structure, comparative suffix.

The consistent application of the "-er" suffix creates a predictable syllable division pattern. The vowel sound in the root word influences the syllable weight and stress.

Detailed Syllable Analysis:

• light - /laɪt/ - Open syllable, stressed. Rule: Onset-Rime structure. The vowel sound /aɪ/ is a diphthong, forming the nucleus of the rime.
• er - /tə/ - Closed syllable, unstressed. Rule: Consonant-Vowel structure. The /t/ forms the onset, and /ə/ the rime. Potential exception: Schwa reduction is common in unstressed syllables.
• than - /ðæn/ - Open syllable, unstressed. Rule: Onset-Rime structure. /ð/ is the onset, /æn/ is the rime.
• air - /eə/ - Open syllable, unstressed. Rule: Onset-Rime structure. /e/ is the onset, /ə/ is the rime. Potential exception: Diphthongization of /e/ to /eə/ is common.

Division Rules Applied:

1. Onset-Rime: Syllables are divided based on the onset (initial consonant sound(s)) and rime (vowel sound and any following consonants).
2. Vowel Nucleus: Each syllable must contain a vowel sound (nucleus).
3. Comparative Suffix Rule: The "-er" suffix typically forms a separate syllable.

Special Considerations:

• The phrase "than air" is a fixed expression, and the syllable division reflects this.
• Regional variations in vowel pronunciation (e.g., /æ/ vs. /ɑː/ in "than") might slightly alter the phonetic realization but not the syllable division.
• The word is a compound adjective, and the syllabification reflects the individual morphemes.

Alternative Pronunciations/Regional Variations:

Some speakers might pronounce "lighter" as /ˈlaɪtər/ with a more distinct /r/ sound, but this doesn't change the syllable division.

Short Analysis:

"Lighter-than-air" is a compound adjective divided into four syllables: light-er-than-air. The primary stress falls on "light". The word is morphologically composed of a root ("light"), a comparative suffix ("-er"), a function word ("than"), and another root ("air"). The syllabification follows standard English rules based on onset-rime structure and vowel nuclei.
