Final answer:
Adding the prefix 'dis' to a word typically changes the meaning to the opposite.
Step-by-step explanation:
When the prefix "dis-" is added to a word, it generally conveys a sense of reversal, negation, or removal. The prefix "dis-" is of Latin origin and is commonly used in English to create opposites or convey a negative sense.
When the prefix 'dis' is added to a word, it typically changes the meaning to the opposite. So, if the word means 'Agree', adding 'dis' to the start of the word would mean 'Not Agree' or 'Disagree'.
