chiefly U.S. spelling of analogue (q.v.).

1826, “an analogous thing,” from French analogue, from Greek analogon (itself used in English from c.1810), from ana “up to” (see ana-) + logos “account, ratio” (see lecture (n.)). Computing sense is recorded from 1946.

An organ or structure similar in function to one in another species but of dissimilar evolutionary origin.

A structural derivative of a parent chemical compound that often differs from it by a single element.

analog or analogue
Adjective Measuring or representing data by means of one or more physical properties that can express any value along a continuous scale. For example, the position of the hands of a clock is an analog representation of time. Compare digital.


An organ or structure that is similar in function to one in another kind of organism but is of dissimilar evolutionary origin. The wings of birds and the wings of insects are analogs.

A chemical compound that has a similar structure and similar chemical properties to those of another compound, but differs from it by a single element or group. The antibiotic amoxicillin, for example, is an analog of penicillin, differing from the latter by the addition of an amino group. Compare homologue.
