Final answer:
The sentence about modern English terms for large bodies of water does not fit with the Old English kennings theme of the paragraph.
Step-by-step explanation:
The sentence that does not belong in the illustration paragraph is: "Now in English when we want to refer to the large bodies of water that separate the continents, we use words such as sea, ocean, or even the deep." This sentence does not fit with the overall theme of Old English kennings and their beautiful and picturesque language. The paragraph focuses on the vivid and creative ways that Old English poetry describes common concepts, such as battle and the sea, using metaphorical language and vivid imagery to convey a sense of beauty and imagination. Mentioning modern English terms for the sea does not contribute to this depiction of Old English literary artistry.
