To put it simply, the word "term" is another word for, well, word. Ultimately, literary terms are words used to describe devices used in literature.

Literary terms are words such as personification, simile, hyperbole, metaphor, and so on. They are used to describe various forms of writing by an author. Let's take a look at personification. The word "personification" is just that, a word or a literary term. The definition of personification is an object, thing, or nonhuman character having human traits. Authors may use examples of personification in their writings. An example of personification used may be "The wind howled through the trees." The wind is the nonhuman and the howling is something that a human may do. Thus, the wind has a human characteristic or is an example of personification.
Let's take a look at another literary term: onomatopoeia. Onomatopoeia is the literary term. The definition is words that have sounds. An example of an onomatopoeia is, "The phone buzzed in my pocket." The word "buzz" is an example of an onomatopoeia because the word "buzz" sounds like the sound buzz.
