The word "expletive" can be understood in two main ways:
Expletives as Fillers: An expletive is a word or phrase that does not add any real meaning to a sentence but is used to fill out the sentence. For example, in the sentence "It is raining," the phrase "It is" is an expletive because it doesn't provide new information about the rain itself.
Expletives as Swear Words: An expletive can also refer to a swear word or a curse word, often used to express strong emotions like surprise or anger. For example, saying "Oh, shoot!" or using a stronger word when something goes wrong.
Understanding the word "expletive" is essential for both writing and speaking.
