Final answer:
No, the phrase 'you take the L out of lover because it's over' is not a pun but a metaphor, as it uses word composition to convey an idea in a figurative manner.
Step-by-step explanation:
The phrase “you take the L out of lover because it's over” is not technically considered a pun. A pun is a form of word play that exploits multiple meanings of a term or similar-sounding words for an intended humorous or rhetorical effect. In this case, removing the letter 'L' from 'lover' to end up with 'over' does not create a new meaning through sound similarity or multiple meanings. Instead, it's a play on the composition of the words to convey a concept metaphorically. Therefore, based on the options provided, the phrase is considered a metaphor. Metaphors in English are very common, and they allow abstract concepts, such as love, to be expressed in more tangible terms.
