IPA: /nɒnˌrɛtrəʊˈæktɪv/
KK: /nɑnˌrɛtroʊˈæktɪv/
This term describes something that does not apply to past events or situations, only affecting future occurrences.
The new law is nonretroactive, meaning it will not change any previous decisions.
Nonretroactive → It is formed from "non-" (meaning not) and "retro-" (meaning backward) and "act" (from Latin "agere", meaning to do) and "-ive" (meaning having the nature of). The word describes something that does not apply to actions or events that occurred in the past.
Think of 'not' ('non-') applying to something that goes 'backward' ('retro-') in time, and that it relates to actions ('act'). This helps you remember that 'nonretroactive' means it does not affect past actions.
