Cycasin is a toxin that can be dangerous if ingested from certain plants.
Cycasin is derived from 'Cycas' (from the genus name of a group of plants known as cycads) and the suffix '-in' (used in chemistry to denote substances). The word refers to a toxic compound found in the seeds of cycad plants.
Think of 'Cycas' as the name of the plant that produces cycasin, and remember that the '-in' suffix indicates a substance, which helps you recall that cycasin is a substance derived from the Cycas plant.
