What kind of figurative language is “Play dead often and long enough and people begin to think you are.” ?

Not knowing the context for this sentence it's hard to know exactly what is implied or referenced by "playing dead," but it's a metaphor for being unresponsive, as in always playing dumb (I dunno), being oblivious to others because someone is listening to ear buds and paying no attention, or something like that.

The figurative language used in the sentence "Play dead often and long enough and people begin to think you are" is a metaphor.

To identify the type of figurative language in a sentence, follow these steps:

1. Read the sentence and identify any words or phrases that are not meant to be taken literally.
In this case, the phrase "play dead" is used metaphorically. It does not mean actually pretending to be dead, but rather metaphorically pretending to be something you are not.

2. Determine the comparison being made between the literal and figurative elements in the sentence.
In this metaphor, the comparison being made is between the act of playing dead and people thinking that you actually are dead. It suggests that if you pretend to be or act in a certain way long enough, others might start to believe it to be true.

3. Confirm that the figurative language used is consistent with the definitions of different types of figurative language.
In this case, a metaphor is used because the comparison is implied directly rather than using words such as "like" or "as." A metaphor states that one thing is another thing, in this case, pretending to be dead is likened to others believing you are actually dead.

So, the type of figurative language used in the sentence is a metaphor.
