Morphology

homologous = homology (semi-transparent) = homo + log + ous

The adjectival relation to 'homology' is predictable ('-ous' forming an adjective), but the combining form 'homo-' and 'log' are technical/Greek-derived elements that may be unfamiliar to general learners.

Etymology

Homologous comes from Greek parts homo- meaning 'same' and -logos meaning 'relation' or 'reason', the same homo- you see in homophone or homogeneous. So in biology homologous describes things (like a bat wing and a human arm) that have the 'same' origin or structure even if they do different jobs.
