Any good anagrams for explanatory power?

Explanatory power is the ability of a hypothesis or theory to effectively explain the subject matter it pertains to. The opposite of explanatory power is explanatory impotence. In the past, various criteria or measures for explanatory power have been proposed. In particular, one hypothesis, theory, or explanation can be said to have more explanatory power than another about the same subject matter if more facts or observations are accounted for; if it changes more "surprising facts" into "a matter of course" (following Peirce); if more details of causal relations are provided, leading to a high accuracy and precision of the description; if it offers greater predictive power, i.e., if it offers more details about what we should expect to see, and what we should not; if it depends less on authorities and more on observations; if it makes fewer assumptions; if it is more falsifiable, i.e., more testable by observation or experiment (following Popper).Recently, David Deutsch proposed that theorists should seek explanations that are hard to vary. By this expression he intends to state that a hard to vary explanation provides specific details which fit together so tightly that it is impossible to change any one detail without affecting the whole theory.
