IPA: //sʌbˈsoʊlər//
KK: /sʌbˈsoʊlər/
Referring to a position directly under the sun or in the area where the sun is directly overhead.
The subsolar point is the location on Earth where the sun is at its zenith.
Subsolar → It is formed from "sub-" (meaning under or below) and "solar" (from Latin "solaris", meaning of the sun). The word "subsolar" refers to a position that is directly beneath the sun.
Think of being 'under' ('sub-') the 'sun' ('solar') — that's what subsolar means.
