In a way that is secondary or supportive to something else.

Subsidiarily → It is formed from "sub-" (meaning under) and "sidium" (from Latin, meaning to sit or settle). The suffix "-arily" (meaning in a manner relating to) indicates a manner of being subordinate or supportive. Thus, "subsidiarily" refers to acting in a supportive or subordinate manner, typically in relation to a primary action or entity.
Think of 'sub-' meaning 'under' and 'sidium' meaning 'to sit' — this helps you remember that 'subsidiarily' refers to acting in a supportive or subordinate way.
