When something is said to be deductive, it is based on a deduction. One has to apply his knowledge and logic to get the required results. Such things that involve or use deduction in reasoning are also referred to as deductive. One can also make use of inferences from general principles. For example: All dogs are animals [premise]; this is a dog; therefore, this is an animal. Here, one arrives at the truth or conclusion by referring to a method.
Another example: All men are apes; this is a man, so this is an ape. This is a logical conclusion but the premise used is absurd. Thus, something that based on deduction from preset premises is called deductive. Example: deductive argument or deductive reasoning. Some of the words that mean deductive are: understandable, consequent, derivable, reasoned, inferential, dogmatic, traceable, assertive, truthful, doctrinal, doctrinaire, theoretical, systematic, inevitable, and canonical.
