8. Definition & Semantics:

• Definition: A diagnostic test that measures the electrical activity of the retina in response to light.
• Grammatical Category: Noun
• Synonyms: ERG testing
• Antonyms: None directly applicable.
• Examples:
  • "The doctor ordered an electroretinography to assess the patient's retinal function."
  • "Electroretinography is a valuable tool in diagnosing inherited retinal diseases."

9. Phonological Comparison:

• Photography: pho-to-gra-phy. Similar suffix "-graphy", stress on the antepenultimate syllable.
• Cardiography: car-di-o-gra-phy. Similar suffix "-graphy", stress on the antepenultimate syllable.
• Radiography: ra-di-o-gra-phy. Similar suffix "-graphy", stress on the antepenultimate syllable.

Syllable Breakdown Details:

• el-ec-tro-re-ti-no-gra-phy
  • el: /ɛl/ - Open syllable, initial consonant cluster. Rule: Consonant clusters are generally broken after the first consonant if possible.
  • ec: /ɛk/ - Closed syllable, consonant ending. Rule: Close syllables are formed when a vowel is followed by a consonant.
  • tro: /troʊ/ - Open syllable. Rule: Vowel followed by consonant(s) and then a vowel in the next syllable.
  • re: /rɛ/ - Open syllable. Rule: Vowel followed by consonant(s) and then a vowel in the next syllable.
  • ti: /tɪ/ - Closed syllable, consonant ending. Rule: Close syllables are formed when a vowel is followed by a consonant.
  • no: /nɒ/ - Open syllable. Rule: Vowel followed by consonant(s) and then a vowel in the next syllable.
  • gra: /ɡrə/ - Open syllable. Rule: Vowel followed by consonant(s) and then a vowel in the next syllable.
  • phy: /fi/ - Closed syllable, consonant ending. Rule: Close syllables are formed when a vowel is followed by a consonant.

Division Rules Applied:

• Onset-Rime Principle: Syllables are structured around an onset (initial consonant(s)) and a rime (vowel and any following consonants).
• Sonority Sequencing Principle: Consonant clusters are broken based on the sonority hierarchy (vowels are more sonorous than consonants).
• Vowel-Centric Syllabification: Each syllable generally contains one vowel sound.

Special Considerations:

The complex consonant clusters at the beginning of the word require careful consideration. The rule of breaking consonant clusters after the first consonant is applied where possible.

Alternative Pronunciations/Regional Variations:

Minor variations in vowel quality (e.g., the "o" in "electro") may occur depending on regional accents. However, the syllable division remains consistent.
