"Kelal UPerat", "Perat UKelal" = Principles followed by Specifications, or Vice Versa, in the Torah
Note: In Kelal-Perat-Kelal, the perat includes specific cases (but excludes most others), and the second kelal expands to include cases which are closely similar to those specific cases.
Kelal and Perat extrapolations are based on the meaning of the Torah's words, rather than textual anomalies [like extra words]: Rashi Zevachim 8b "Ela"
How this principle interacts with the principle that there are Out-of-Order sections of the Torah: Pesachim 6b

Using a Kelal uPerat uKelal where the first and second kelalim are of different natures: Keritot 21a; Zevachim 4b, 8b
We don't extrapolate from a Kelal if it is not "malei", incomplete: Zevachim 4b

Example: Temurah 13b
"Machria" - A 3rd, Compromising Opinion
This method only works if the Machria is a true Compromise, and isn't simply expressing a 3rd opinion: Pesachim 13a, Tos. Pesachim 21a #1
