This root conveys the core concept of microbial contamination and organic decomposition. Examples include sepsis, septic, antiseptic, aseptic, septicemia.
a-
Comes from the Greek prefix 'a-' (alpha privative), meaning 'without', 'not', or 'lacking'. It negates the meaning of the root it attaches to. Examples include atypical, amoral, asymmetrical, asexual, aseptic.
