International Dictionary of Medical and Scientific Affixes

• Adelpho- — A prefixoid or scholarly combining form used to build scientific terms in the fields of biology, genetics, or medicine, meaning 'brother', 'twin', 'similar', or 'double'. In the structure of neologisms, it adds a nuance of close relation, tight structural associations, or twinship between the component elements of a system.
• Adeno- — A primary element of scholarly compounding that introduces into the resulting term a structural reference to a gland, lymph node, or glandular tissue; utilized exclusively for forming medical and biological neologisms (such as adenocarcinoma, adenofibroma, or adenopathy), indicating the anatomical origin or location of a physiological or pathological process.
• Asporo- — A scientific combining form used as a prefixoid in international scientific terminology to indicate the absence of spores, the lack of spore-reproduction capacity, or non-sporulation; it originates from combining the privative prefix 'a-' with the Greek root 'spora' (seed), serving to form biochemical and medical neologisms describing organisms or cells that do not generate resistance structures.
