A verb is conjugated in order to provide it with different functions in a sentence or phrase.
It is modified according to voice, aspect, emphasis, or modality with the use of auxiliary verbs
which provide it with additional meaning.
A verb that is used to indicate modality is called a modal verb. It is used to convey likelihood, ability, permission, and obligation.
It provides knowledge about the purpose of the main verb that follows it which may be a possibility or a necessity,
a likelihood, certainty, duty, ability, or permission.
Examples of modal verbs are the words “will” and “may.”
The past tense form of the word “will” is “would” while the past tense form of the word “may” is “might.”
These words are used to create conditional verb forms.
The word “would” is the more commonly used of the two, and it indicates a past repetition.
It is used to express an intent, wish or desire, willingness, preference, or intention.
In a conditional sentence, it is used to express a possibility. (가정법일 때는 가능성 표현에 쓰임)
