adjunctive

Helping the main

Adjunctive describes something added to support or supplement a primary element rather than serving as the main thing itself.

Most common in medical contexts, where adjunctive therapy or treatment accompanies the principal treatment: Radiation was used as adjunctive therapy following surgery.

The word emphasizes the secondary, supporting role of whatever it modifies.
