no/noʊ/

Stressed, open syllable.

e/iː/

Open syllable.

tha/θə/

Open syllable.

nol/noʊl/

Closed syllable.

a/ə/

Open syllable, schwa.

Morphemic Breakdown

Morphemes are the smallest meaningful parts of words: prefixes (beginning), roots (core meaning), and suffixes (ending)

mono-(prefix)
+
ethanol-(root)
+
-amine(suffix)

Prefix: mono-

Greek origin, meaning 'one' or 'single', quantitative prefix.

Root: ethanol-

Derived from ethane and ol, representing the ethyl alcohol base.

Suffix: -amine

Latin origin, indicating a nitrogen-containing functional group.

Meanings & Definitions
noun(grammatical role in sentences)

A viscous, colorless organic compound used as an absorbent for acid gases, a surfactant, and a chemical intermediate.

Examples:

"Monoethanolamine is commonly used in gas purification processes."

"The reaction involved the use of monoethanolamine as a catalyst."

Vowel Division

Syllables are generally formed around vowel sounds.

Onset-Rime

Syllables consist of an onset (initial consonant(s)) and a rime (vowel and any following consonants).

Stress Placement

English generally favors stress on the penultimate syllable, unless other factors intervene.

Analysis Summary

Summary:

Monoethanolamine is a seven-syllable word (mo-no-e-tha-nol-a-mine) with primary stress on the penultimate syllable. It's morphologically composed of the prefix 'mono-', the root 'ethanol-', and the suffix '-amine'. Syllabification follows standard English vowel division and onset-rime principles.

Detailed Analysis:

Linguistic Analysis of "monoethanolamine" (English - US)

1. Pronunciation Examination:

The word "monoethanolamine" is pronounced /ˌmɒnoʊˌiːθəˈnoʊləmiːn/ in General American English. It presents challenges due to its length and the presence of multiple vowels and diphthongs.

2. Syllable Division:

Following English syllabification rules, the word divides as follows: mo-no-e-tha-nol-a-mine.

3. Morphemic Analysis:

  • Prefix: mono- (Greek, meaning "one" or "single"). Morphological function: indicates quantity.
  • Root: ethanol- (derived from ethane + ol). Ethane is from the chemical nomenclature system, and ol is a suffix denoting an alcohol.
  • Suffix: -amine (Latin, meaning "containing nitrogen"). Morphological function: indicates a functional group in organic chemistry, specifically an amine.

4. Stress Identification:

The primary stress falls on the penultimate syllable: /ˌmɒnoʊˌiːθəˈnoʊləmiːn/. Specifically, it's on the "no" in "no-la".

5. Phonetic Transcription:

/ˌmɒnoʊˌiːθəˈnoʊləmiːn/

6. Edge Case Review:

The sequence "ea" can sometimes form a diphthong, but in this case, it's broken across syllables ("e-tha"). The "ol" sequence is generally a single syllable unit, but the following "a" necessitates a syllable break.

7. Grammatical Role:

"Monoethanolamine" primarily functions as a noun, referring to a specific chemical compound. It doesn't typically change its syllabification or stress pattern when used in different grammatical contexts.

8. Definition & Semantics:

  • Definition: A viscous, colorless organic compound with the formula C₂H₇NO. It is used as an absorbent for acid gases, a surfactant, and a chemical intermediate.
  • Grammatical Category: Noun
  • Synonyms: 2-Aminoethanol, β-Aminoethanol
  • Antonyms: (Not applicable - it's a specific chemical compound)
  • Examples:
    • "Monoethanolamine is commonly used in gas purification processes."
    • "The reaction involved the use of monoethanolamine as a catalyst."

9. Phonological Comparison:

  • Similar Word 1: "diethanolamine" (di-e-tha-nol-a-mine) - Similar syllable structure, with the prefix changing to "di-". Stress remains on the penultimate syllable.
  • Similar Word 2: "triethanolamine" (tri-e-tha-nol-a-mine) - Again, similar structure, with the prefix changing to "tri-". Stress pattern is consistent.
  • Similar Word 3: "ethanolamine" (e-tha-nol-a-mine) - This word lacks the "mono-" prefix. The stress pattern shifts to the antepenultimate syllable. This demonstrates how prefixes can influence stress placement.

10. Syllable Analysis Breakdown:

Syllable IPA Transcription Description Rule Applied Exceptions/Special Cases
mo /moʊ/ Open syllable Vowel followed by consonant None
no /ˈnoʊ/ Stressed, open syllable Vowel followed by consonant None
e /iː/ Open syllable Vowel None
tha /θə/ Open syllable Consonant-vowel None
nol /noʊl/ Closed syllable Vowel followed by consonant cluster None
a /ə/ Open syllable Schwa vowel None
mine /miːn/ Closed syllable Diphthong followed by consonant None

11. Division Rules Applied:

  • Vowel Division: Syllables are often formed around vowel sounds.
  • Onset-Rime: Syllables consist of an onset (initial consonant(s)) and a rime (vowel and any following consonants).
  • Stress Placement: English generally favors stress on the penultimate syllable, unless other factors intervene.

12. Special Considerations:

The length of the word and the presence of multiple vowels require careful application of syllabification rules. The "ea" sequence is a potential point of ambiguity, but is resolved by breaking it across syllables.

13. Alternative Pronunciations/Regional Variations:

While the provided pronunciation is standard, slight variations in vowel quality may occur depending on regional accents. These variations would not significantly alter the syllable division.

What is hyphenation

Hyphenation is the process of dividing words across lines in print or on websites. It involves inserting hyphens (-) where a word breaks to continue on the next line.

Proper hyphenation improves readability by reducing the unevenness of word spacing and unnecessary large gaps. It also helps avoid confusion that may occur when part of a word carries over. Ideal hyphenation should break words according to pronunciation and syllables. Most word processors and publishing apps have automated tools to handle hyphenation effectively based on language rules and dictionaries. Though subtle, proper hyphenation improves overall typography and reading comfort.
