Etymology
The word 'instillation' has a literal and transparent journey from Latin to English. It originates from the Latin verb instillāre, which is a compound of the prefix in- ("into") and the verb stillāre ("to drip, drop"). The core image is of causing a liquid to fall in drops into something. This concrete meaning was carried directly into medical and scientific English. Over time, the concept was metaphorically extended to the gradual and subtle introduction of non-physical things, such as ideas, feelings, or attitudes, into a person's mind, mirroring the slow, penetrating action of a liquid drip. The suffix -ation consistently nominalizes the action throughout its history.
