conclude

close, end, conclude, finish, complete, terminate mean to bring or come to a stopping point or limit. close usually implies that something has been in some way open as well as unfinished <close a debate>. end conveys a strong sense of finality <ended his life>. conclude may imply a formal closing (as of a meeting) <the service concluded with a blessing>. finish may stress completion of a final step in a process <after it is painted, the house will be finished>. complete implies the removal of all deficiencies or a successful finishing of what has been undertaken <the resolving of this last issue completes the agreement>. terminate implies the setting of a limit in time or space <your employment terminates after three months>.

infer, deduce, conclude, judge, gather mean to arrive at a mental conclusion. infer implies arriving at a conclusion by reasoning from evidence; if the evidence is slight, the term comes close to surmise <from that remark, I inferred that they knew each other>. deduce often adds to infer the special implication of drawing a particular inference from a generalization <denied we could deduce anything important from human mortality>. conclude implies arriving at a necessary inference at the end of a chain of reasoning <concluded that only the accused could be guilty>. judge stresses a weighing of the evidence on which a conclusion is based <judge people by their actions>. gather suggests an intuitive forming of a conclusion from implications <gathered their desire to be alone without a word>.

Sir Thomas More is the first writer known to have used both infer and imply in their approved senses (1528). He is also the first to have used infer in a sense close in meaning to imply (1533). Both of these uses of infer coexisted without comment until some time around the end of World War I. Since then, senses 3 and 4 of infer have been frequently condemned as an undesirable blurring of a useful distinction. The actual blurring has been done by the commentators. Sense 3, descended from More's use of 1533, does not occur with a personal subject. When objections arose, they were to a use with a personal subject (now sense 4). Since dictionaries did not recognize this use specifically, the objectors assumed that sense 3 was the one they found illogical, even though it had been in respectable use for four centuries. The actual usage condemned was a spoken one never used in logical discourse. At present sense 4 is found in print chiefly in letters to the editor and other informal prose, not in serious intellectual writing. The controversy over sense 4 has apparently reduced the frequency of use of sense 3.

The Latin word claudere, meaning “to close” or “to shut,” gives us the root clud. To exclude is to shut another out of a group. To include is to shut someone into a group. To conclude, or bring something, such as a speech, to an end, is to close it.
