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

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.
