Homogenous
Extracted from the Wikipedia article Homogeneity and heterogeneity.
Etymology and spelling
Alternate spellings omitting the last -e- (and the associated pronunciations) are common, but incorrect: homogenous is strictly a biological/pathological term which has largely been replaced by homologous. But use of homogenous to mean homogeneous has seen a rise since 2000, enough for it to now be considered an "established variant". Similarly, heterogenous is a spelling traditionally reserved to biology and pathology, referring to the property of an object in the body having its origin outside the body.
