Final answer:
The error in saying 'dunno' instead of 'don't know' is a matter of pronunciation.
Step-by-step explanation:
The error in saying 'dunno' instead of 'don't know' is a matter of pronunciation. Pronunciation refers to the way words are spoken and includes elements such as the sounds, stress, and rhythm of speech.
In this case, the error lies in pronouncing the words 'don't know' as 'dunno,' which is a more informal and colloquial way of speaking. It is important to be aware of and practice proper pronunciation to ensure clear and effective communication.
An example of another pronunciation error could be pronouncing 'asked' as 'aksed.' In this case, the 's' sound is being replaced by a 'k' sound, which is incorrect.
