Introduction
In the realm of phonology, where sounds dance and interact, dissimilation plays a vital role. It’s the understudy to the better-known assimilation, working to differentiate sounds rather than unite them.
Dissimilation is a process that changes one sound in a word to become less similar to another sound within the same word or nearby words. This phenomenon, often subtle, is a key part of why languages evolve and how pronunciations shift over time.
Understanding dissimilation can significantly improve your comprehension of spoken English and sharpen your pronunciation skills.
This article will delve into the intricacies of dissimilation, exploring its various types and providing numerous examples. By understanding the underlying principles and observing real-world applications, you’ll gain a deeper appreciation for the dynamic nature of the English language and the forces that shape its pronunciation.
Whether you’re a student, teacher, or simply a language enthusiast, this comprehensive guide will equip you with the knowledge to recognize and understand dissimilation in English.
Definition of Dissimilation
Dissimilation is a phonological process in which two similar sounds in a word become less alike. It’s the opposite of assimilation, where sounds become more similar.
The primary function of dissimilation is to ease pronunciation by reducing articulatory effort or perceptual ambiguity. Dissimilation can occur between adjacent sounds or sounds separated by one or more syllables within a word.
Key Features of Dissimilation:
- Phonological Process: A systematic change in the sounds of a language.
- Opposite of Assimilation: Sounds become less, not more, similar.
- Ease of Pronunciation: Simplifies articulation.
- Perceptual Clarity: Reduces confusion between similar sounds.
- Context Dependent: Occurs under specific phonological conditions.
Dissimilation can be classified based on several criteria, including the specific phonetic features that change (e.g., place of articulation, manner of articulation, voicing) and the distance between the sounds involved. The process is often subtle and may not be immediately obvious, but it plays a significant role in the evolution and variation of language.
Structural Breakdown
The structure of dissimilation involves several key components that determine how and why the sound change occurs. Understanding these elements will help you identify and analyze instances of dissimilation in English.
1. Target Sound: This is the sound that undergoes the change. It’s the sound that becomes less similar to another sound in the word.
2. Trigger Sound: This is the sound that causes the change in the target sound. Its presence influences the pronunciation of the target sound.
3. Feature Change: This refers to the specific phonetic feature that is altered. For instance, a sound might change in its place of articulation (e.g., from alveolar to velar), its manner of articulation (e.g., from a stop to a fricative), or its voicing (e.g., from voiced to voiceless).
4. Distance: This refers to the separation between the target and trigger sounds. Dissimilation can occur between adjacent sounds (contact dissimilation) or sounds separated by one or more syllables (distance dissimilation).
5. Environment: This includes the surrounding sounds and the position of the sounds within the word. The specific environment can influence whether dissimilation occurs and the type of change that takes place.
For example, in the word “pilgrim,” the first /r/ sound can sometimes be dropped, resulting in a pronunciation closer to “pilgrim.” Here, the first /r/ (target sound) becomes less like the second /r/ (trigger sound) due to their proximity. The feature change is the deletion of the /r/ sound, and the distance between the sounds is relatively short.
Types of Dissimilation
Dissimilation can be categorized based on various factors, including the phonetic feature that changes and the distance between the sounds involved. Here are some of the primary types of dissimilation:
Place Dissimilation
Place dissimilation occurs when the place of articulation of one sound changes to become less similar to the place of articulation of another sound. This often involves shifting the articulation from one part of the mouth to another (e.g., from the front to the back).
Manner Dissimilation
Manner dissimilation involves a change in the manner of articulation. For instance, a stop sound might become a fricative, or a nasal sound might become an oral sound.
This type of dissimilation alters how the airflow is managed during the production of the sound.
Voicing Dissimilation
Voicing dissimilation involves a change in the voicing of a sound. A voiced sound (where the vocal cords vibrate) might become voiceless (where the vocal cords do not vibrate), or vice versa.
This type of dissimilation is often influenced by the voicing of nearby sounds.
Distance Dissimilation
Distance dissimilation occurs when the sounds involved are separated by one or more syllables. This type of dissimilation is less common than contact dissimilation but can still occur, especially in longer words.
Examples of Dissimilation
To illustrate the different types of dissimilation, let’s examine several examples in English. These examples will help you recognize and understand how dissimilation affects pronunciation.

Usage Rules
Dissimilation is not governed by strict rules in the same way that grammatical structures are. Instead, it is influenced by phonetic context, ease of articulation, and historical language changes.
However, some general tendencies can be observed:
- Ease of Articulation: Dissimilation often occurs to simplify pronunciation, especially when similar sounds are close together.
- Dialectal Variation: Dissimilation patterns can vary significantly between different dialects of English.
- Informal Speech: Dissimilation is more common in informal speech and may be less frequent in formal or careful pronunciation.
- Historical Change: Many instances of dissimilation have become fixed in the language over time, leading to changes in the standard pronunciation of words.
- Phonetic Environment: The surrounding sounds can influence whether dissimilation occurs.
It’s important to note that dissimilation is not always predictable, and some instances may be idiosyncratic to specific words or dialects. Exposure to a wide range of spoken English and careful attention to pronunciation patterns can help you develop an intuitive understanding of dissimilation.
Common Mistakes
When learning about dissimilation, it’s easy to make certain mistakes. Here are some common errors and how to avoid them:
- Misidentifying Assimilation as Dissimilation: Confusing the two processes is a common error. Remember that assimilation is when sounds become more similar, while dissimilation is when they become less similar.
- Overgeneralizing Dissimilation: Assuming that dissimilation always occurs in certain contexts can lead to incorrect pronunciations. Dissimilation is context-dependent and not always predictable.
- Ignoring Dialectal Variation: Dissimilation patterns can vary between dialects. Be aware that what is considered standard pronunciation in one dialect may not be in another.
- Applying Dissimilation to Written Forms: Dissimilation primarily affects pronunciation. Do not alter the spelling of words based on dissimilation.
Examples of Correct vs. Incorrect Usage:
| Word | Incorrect (Based on Misunderstanding) | Correct (With Dissimilation) | Explanation |
|---|---|---|---|
| Probably | Probbably (Misunderstanding the pattern) | Probly (Correct Dissimilation) | The vowel sound is dropped for ease of pronunciation. |
| Comfortable | Comfrtable (Ignoring the vowel sound) | Comfterble (Correct Dissimilation) | The /f/ sound replaces /ər/. |
| Interesting | Intersting (Trying to force the pattern) | Inneresting (Correct Dissimilation) | The /t/ sound is dropped in certain pronunciations. |

- Is dissimilation a conscious process?
No, dissimilation is generally an unconscious process that occurs naturally in speech. Speakers are typically not aware that they are changing sounds to make them less similar.
- Why does dissimilation occur?
Dissimilation occurs to ease pronunciation, reduce articulatory effort, and improve perceptual clarity. It can also be influenced by historical language changes and dialectal variations.
- Are there specific rules for dissimilation?
Dissimilation is not governed by strict rules in the same way that grammatical structures are. Instead, it is influenced by phonetic context, ease of articulation, and historical language changes.
- How can I identify dissimilation in spoken English?
Listen carefully to the pronunciation of words and phrases, paying attention to subtle changes in sounds. Compare the actual pronunciation with the expected pronunciation based on spelling and standard phonetic rules. Exposure to a wide range of spoken English and careful attention to pronunciation patterns can help.
- Does dissimilation affect spelling?
Dissimilation primarily affects pronunciation and does not typically affect spelling. The written form of a word usually remains the same, even if its pronunciation changes due to dissimilation.
- Is dissimilation more common in certain dialects of English?
Yes, dissimilation patterns can vary significantly between different dialects of English. Some dialects may exhibit more frequent or different types of dissimilation compared to others.
- Can dissimilation change over time?
Yes, dissimilation patterns can evolve over time, leading to changes in the standard pronunciation of words. Some instances of dissimilation may become fixed in the language, while others may fade away.
