  "definition": "The atom or group of atoms that forms a new bond to a substrate in a chemical reaction, particularly in substitution reactions. This group is typically a nucleophile in nucleophilic substitution or an electrophile in electrophilic substitution. Its identity and reactivity significantly influence the reaction rate and mechanism.",
