Sewer lines?

SEAMS

["Think about what a person who sews creates, not the underground pipes. What are the lines called that a sewer makes with thread?"]

The clue "Sewer lines?" leads to the answer "SEAMS" through a clever play on words. Here's the breakdown: 1. **Surface Meaning**: The clue initially suggests that the answer might be related to pipes or conduits found in a sewer system. 2. **Wordplay**: The clue uses a pun on the word "lines." In the context of a sewer, "lines" could refer to pipes. However, "lines" can also refer to linear marks or features in other contexts. 3. **Alternative Meaning**: The word "sewer" can be interpreted not just as the underground waste system, but also as someone who sews. In this context, "lines" would refer to the lines created by sewing, which are "seams." Therefore, the clue "Sewer lines?" cleverly leads to "SEAMS" by playing on the double meaning of the word "sewer" and the context-specific interpretation of "lines."
