Hyphenation ofучебно-показательный

Linguistic Analysis of "учебно-показательный" (uchebno-pokazatel'nyy)

1. Examination & Pronunciation:

The word "учебно-показательный" is a complex adjective in Russian, meaning "educational-demonstrative" or "didactic." It's formed by compounding two stems. Pronunciation involves careful attention to vowel reduction in unstressed syllables, a common feature of Russian phonology.

2. Syllable Division:

Following Russian syllabification rules, which prioritize the sonority peak within a syllable, the word breaks down as follows (using only original letters):

у-чеб-но-по-ка-за-тель-ный

3. Morphemic Analysis:

• Prefix: учеб- (ucheb-) - Derived from "ученик" (uchenik - student). Indicates relation to learning or education.
• Root: показ- (pokaz-) - From "показывать" (pokazyvat' - to show, to demonstrate). Indicates the act of showing or demonstrating.
• Suffix: -тельн- (-tel'n-) - A suffix forming qualitative adjectives, indicating a characteristic or quality.
• Suffix: -ый (-yy) - A standard adjectival ending, indicating masculine singular nominative case.

4. Stress Identification:

The primary stress falls on the penultimate syllable: по-ка-за-тель-ный.

5. Phonetic Transcription:

/ʊˈt͡ɕebnə pəkɐˈzʲatʲɪlʲnɨj/

6. Edge Case Review:

The hyphenated structure presents a slight edge case. Russian compound words are often treated as single words for syllabification purposes, but the hyphen maintains a visual separation reflecting the morphemic boundaries. Vowel reduction is significant in unstressed syllables.

7. Grammatical Role:

The word primarily functions as a qualitative adjective. Its syllabification and stress remain consistent across different grammatical cases and genders, though vowel reduction patterns will vary slightly depending on the case ending.

8. Definition & Semantics:

• Definition: Educational, demonstrative, didactic, instructional. Relating to or serving to educate or demonstrate.
• Grammatical Category: Adjective
• Synonyms: образовательный (obrazovatel'nyy - educational), демонстрационный (demonstratsionnyy - demonstrative)
• Antonyms: практический (prakticheskiy - practical)
• Examples:
  • "учебно-показательное пособие" (uchebno-pokazatel'noye posobiye) - "an educational-demonstrative manual"
  • "учебно-показательное выступление" (uchebno-pokazatel'noye vystupleniye) - "an educational-demonstrative performance"

9. Phonological Comparison:

• образовательный (obrazovatel'nyy): о-бра-зо-ва-тель-ный. Similar syllable structure with suffixes. Stress on the penultimate syllable.
• демонстрационный (demonstratsionnyy): де-мон-стра-ци-он-ный. Similar suffix structure (-tsionnyy). Stress on the antepenultimate syllable.
• информационный (informatsionnyy): ин-фор-ма-ци-он-ный. Similar suffix structure (-tsionnyy). Stress on the antepenultimate syllable.

The differences in stress placement are due to the varying weight and sonority of the syllables preceding the stressed syllable. "учебно-показательный" has a lighter syllable structure before the stress, leading to penultimate stress.

10. Division Rules:

• Sonority Peak: Syllables are formed around a sonority peak (vowel or sonorant consonant).
• Consonant Clusters: Consonant clusters are generally split according to the principle of maximal onset.
• Vowel Reduction: Unstressed vowels are reduced, influencing the perceived syllable boundaries.
• Compound Word Syllabification: Compound words are syllabified based on the individual morphemes, but treated as a single unit for stress assignment.

11. Special Considerations:

The hyphenated nature of the word is a key consideration. While it doesn't alter the core syllabification rules, it highlights the compound structure. Vowel reduction is a significant factor in pronunciation and can subtly affect the perceived boundaries between syllables.

12. Alternative Pronunciations/Regional Variations:

Regional variations in vowel reduction might exist, but the core syllabification remains consistent. Some speakers might slightly lengthen or shorten certain vowels, but this doesn't fundamentally change the syllable structure.
