Etymology
The word "phase-in" is a modern English compound, combining the noun "phase" with the adverbial particle "in." The term "phase" originates from the Greek phasis, meaning "appearance" or "aspect," particularly of a planet or star, which evolved through Latin and French to denote a distinct stage in a process. The particle "in," of Germanic origin, signifies movement into a condition or state. The compound "phase-in" logically constructs the concept of bringing something into operation through successive, distinct stages, moving from the literal astronomical sense of phases to an abstract managerial or procedural term.
Analysis

phase: From Greek phasis (appearance), via Latin phasis and French phase. Functions as the core noun meaning a distinct stage or period.
in: From Old English in (in, into). Functions as an adverbial particle indicating direction or introduction.
