Fill in the blank with the correct option. The adverb form of the adjective pretty is [Fill-Regular].
 

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.’ is rewritten as ‘The man drove away angrily.’

‘The boy stared at the food in an exceedingly hungry manner’ may 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 the present rule. There are adverbs that don't end in ‘-ly’ like 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 doesn't end in ‘-ly’. The suffixes of adverbs aren't the identical across the board, they're subject to alter.


There is no thanks to guess these suffixes and also the best thanks 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 straightforward suffix.
The correct answer is option ‘c’.

Note: Use the bottom adjective as a place to begin and add the acceptable suffix.
