IPA: /ˌpriːˈɒpəˌreɪʃənl/
KK: /priˈoʊpəˌreɪʃənl/
Relating to a stage in child development where thinking is not yet logical and children struggle to understand symbols and concepts.
During the preoperational stage, children often think in very concrete terms and have difficulty with abstract ideas.
Preoperational → It is formed from "pre-" (meaning before) and "operational" (from Latin "operari", meaning to work or perform). The term refers to a stage of cognitive development that occurs before the ability to perform operations or logical thinking is fully developed.
Think of 'pre-' meaning before and 'operational' relating to working or performing — this helps you remember that 'preoperational' refers to the stage before one can fully perform logical operations.
