Question

Fill in the blank with the correct option. The adverb form of the adjective pretty is ________.

a. prettyful
b. prettiness
c. prettily
d. pretty

Answer 1

Hint: With the simple addition of the appropriate suffix, the adjective ‘pretty’ can be converted into an adverb.

Complete step-by-step answer:

 Adverbs are words that describe a verb or an adjective. Most adverbs are formed by adding the suffix ‘-ly’ to a base adjective.
For example:

‘The man drove away in an angry manner.’ can be rewritten as ‘The man drove away angrily.’

‘The boy stared at the food in a hungry manner’ can be rewritten as ‘The boy stared at the food hungrily.’

The adjective ‘angry’ becomes the adverb ‘angrily’ and ‘hungry’ becomes ‘hungrily’ by adding the suffix of ‘-ly’. However, there are exceptions to this rule. There are adverbs that do not end in ‘-ly’ such as quite, more, less, etc.

For example:
The food was quite good.

In this case, the word ‘quite’ is an adverb because it describes the adjective ‘good’, but does not end in ‘-ly’. The suffixes of adverbs are not the same across the board, they are subject to change.


There is no way to guess these suffixes and the best way to correctly guess them is to memorize them. The given sentence contains the adjective ‘pretty’. So, the adjective ‘pretty’ would become the adverb ‘prettily’ by adding a simple suffix.
The correct answer is option ‘c’.

Note: Use the base adjective as a starting point and add the appropriate suffix.
