Which action is best associated with the term 'infuse'?

The term 'infuse' is best associated with the action of 'fill completely.' This word typically conveys the idea of introducing something into another thing to fill it, often in a way that permeates or enhances the latter. For example, when we say a tea is infused with flavors, we mean that the flavors are introduced into the tea and permeate throughout, effectively filling the beverage with those tastes.

In various contexts, 'infuse' can also apply to infusing ideas or qualities into a culture or environment, again reflecting the sense of filling or saturating something with a particular essence or influence. This aligns closely with the idea of 'filling completely,' as it embodies the essence of fully integrating one element into another.
