Other forms: abductions
In logic, abduction is reasoning to the best available explanation. Abductive reasoning, an abduction rather than a deduction, argue by abduction.
It is the third kind of inference after deduction, which is certain, and induction, which generalises. Abduction takes an observation and proposes the most plausible cause — it is how doctors diagnose and how detectives work, and it can always be wrong. Charles Sanders Peirce named it. The other and far commoner sense is kidnapping: the abduction of a child, an alleged abduction. Note abduct and abductor.
ab-DUCT-ion → a DUCK
A van pulls up beside the pond, a duck is pushed into the back, and by morning the water is empty and the bread is still on the grass.

Latin abductio means a leading away — ab-, away, plus ducere, to lead. The kidnapping sense is the literal one, and Peirce chose the word for logic because the reasoning leads you away from the evidence to a cause behind it.
