IPA: /tɒkˈsɪkəsɪs/
KK: /tɑk'sɪkoʊsɪs/
A medical condition that occurs due to exposure to toxic substances or poisons.
The patient was diagnosed with toxicosis after ingesting a harmful chemical.
Toxicosis is formed from "toxicum" (from Latin, meaning poison) and the suffix "-osis" (from Greek, meaning condition or process). The word describes a condition resulting from exposure to poison.
Think of 'toxic' as relating to 'poison' and '-osis' indicating a condition, so toxicosis refers to a condition caused by poison.
