heterologous positive

Morphology

heterologous = hetero + log + ous

The meaning is compositionally 'different' (hetero-) + a technical combining form (-log-) + adjectival -ous, so the general idea is inferable but the combining form is technical and may not be obvious to average learners.

Etymology

The word heterologous begins with hetero- meaning 'different', and it is the opposite of homologous, which means 'same origin'. So heterologous describes tissue, cells, or molecules that come from a 'different' species or origin, like a transplant from another animal.
