🎤Pronunciation
🌳Etymology
Origin
Phase derives from Greek 'phasis' (appearance, manifestation), originally referring to the visible appearances or stages of the moon. The term evolved to denote any distinct stage or period in a process, and when combined with the preposition 'in', the phrasal verb 'phase in' acquired the meaning of introducing or incorporating something gradually into operation.
Breakdown
phase (from Greek phasis: appearance, stage) + in (preposition: into, toward the inside). The combination creates a phrasal verb meaning to introduce or bring something into effect gradually.
