classification

This word is most commonly used in formal or professional contexts, such as in science, libraries, or government security. When referring to the process of organizing things (like animals or books), it can be either countable or uncountable depending on if you are talking about one specific system or the general act of sorting. In a military or government context, 'classification' refers specifically to secrecy levels. If someone says a document is 'classified', they mean it is secret.

Fatima uses the phrasal verb 'bogged down' to describe being overwhelmed by the complexity of the taxonomic system (classification), while Maya's response reflects her blunt, efficiency-focused personality.
