Minor: Some reciters are teachers.
Major: No poet is a reciter.
Conclusion: Some teachers are not poets.
The minor supplies reciters who are teachers. The universal negative major excludes every reciter from being a poet, so those particular teachers are not poets.
This is a particular negative conclusion. It cannot be strengthened to “No teacher is a poet,” since the premises say nothing about all teachers.
