Definition

Meaning

To lie on top of or cover something, often in a physical or metaphorical sense of covering or overlaying.

In geology, it refers to a stratum or layer of rock that lies over another. It can also mean to smother or suffocate by lying upon. Metaphorically, it can refer to an abstract layer of meaning or influence that exists on top of something else.

Linguistics

Semantic Notes

Often confused with 'overlay', but 'overlie' is specifically about position (to lie over), typically suggesting direct contact and being a permanent or inherent part of the structure. 'Overlay' often suggests an added or applied layer. The past tense and past participle are 'overlay' and 'overlain', which contributes to confusion.
