instillation singular
instillations plural

Morphology

instillation = instill (semi-transparent) = instill + ation

The noun is formed by '-ation' from 'instill', but the sense 'a liquid administered drop by drop' is a metonymic extension from the action to the substance and may not be directly inferable by all learners.

Etymology

Instillation comes from the same Latin parts in- 'into' and stilla 'drop', and it is the same root found in instill and distill. So an instillation can also mean the liquid 'drop' or drops that are given as medicine.
