IPA: /ˌoʊvərˈskeɪld/
KK: /oʊvərskeɪld/
Larger than what is considered normal or appropriate in size.
The overscaled building towered over the surrounding structures, making them look small in comparison.
Overscaled → It is formed from "over-" (meaning excessively or too much) and "scaled" (from the root "scale" which comes from Latin "scala", meaning a ladder or a series of steps). The word "overscaled" means excessively large or disproportionate in size, as if it has been scaled up too much.
Think of something being made 'too much' ('over-') larger than it should be, like climbing a 'ladder' ('scala') that is too high — that's why overscaled means excessively large.
