What is Sentence Stress?
English is a language that is not just spoken but almost sung. Why? Because English operates on stress patterns, making it sound natural and fluent. If all words in a sentence were stressed equally, it would sound robotic and unnatural. This is where the concept of sentence stress in phonetics and phonology comes into play.
Types of Words
- Content Words: These are usually stressed and include:
- Nouns
- Adjectives
- Adverbs
- Main verbs
- Question words
- Negative auxiliary and modal verbs
- Negative words in general
- Function Words: These are typically unstressed and include:
- Articles
- Auxiliary verbs
- Modal verbs
- Forms of to be
- Pronouns
- Prepositions
- Conjunctions
The Rule of Sentence Stress
Content words are stressed, while function words are unstressed and shortened.
Shortening Function Words
Unstressing function words involves two key processes:
- Deletion of certain consonants
- Shortening of long vowels
Characteristics of Stressed and Unstressed Words
- Stressed: High pitch, high volume, clear, long, and pronounced normally.
- Unstressed: Low pitch, low volume, unclear, short, and pronounced faster.
Practical Exercise: Sentence Stress
Let’s practice with the following sentences. There are three content words in each sentence, and the stress falls on these words. Pronounce them clearer, louder, and longer, while function words are shortened or have consonants removed.
- Cats Chase Mice
- The cats chase the mice.
- The cats have chased the mice.
- The cats have been chasing the mice.
- The cats might have been chasing the mice.
- The cats could have been chasing the mice.
- The cats should have been chasing the mice.
Process Breakdown: Shortening Examples
Here’s how function words are shortened in connected speech:
- Have: /hæv/ → drop "h" and "v" → /ə/ (schwa sound).
- Been: /biːn/ → shorten /iː/ → /bɪn/.
- Might have been: /maɪt həv bɪn/ → /maɪtəbɪn/.
- Should have been: /ʃʊd həv bɪn/ → /ʃʊdəbɪn/.
- Could have been: /kʊd həv bɪn/ → /kʊdəbɪn/.
- Couldn't have been: /kʊdnt həv bɪn/ → /kʊnəbɪn/.
- Shouldn't have been: /ʃʊdnt həv bɪn/ → /ʃʊnəbɪn/.
Rule of Phrasal Verbs in Sentence
Correct pronunciation is crucial because stressing the preposition or using the wrong vowel sound can change the meaning entirely. Prepositions inside phrasal verbs are stressed. Let’s compare:
- Phrasal Verb: Turn on (/tɜːn ɒn/): The preposition on is pronounced with a long vowel (/ɒn/), meaning to switch on an electrical device.
- Non-Phrasal Usage: Turn on (/tɜːn ən/): If on is pronounced with a schwa (/ən/), it changes the meaning to “turn around” and is not interpreted as a phrasal verb.
Practice Tips
- Use a rubber band: Stretch it on stressed words and relax it on unstressed words.
- Tap with a pen or marker: Tap on each stressed word as you read the sentence.
Conclusion
Mastering sentence stress is essential for sounding natural in English. Practice regularly, focusing on stressing content words and shortening function words, and you'll soon notice a significant improvement in your fluency!
