Relating to a shadow or a faint outline; it can also mean something that is only partially revealed or suggested.
The adumbrative remarks in his speech hinted at future plans without revealing too much detail.
Adumbrative is formed from "ad-" (meaning to or toward) and "umbra" (meaning shadow). The word describes something that casts a shadow or provides a faint outline, suggesting a preliminary or partial representation.
Think of something that gives a 'shadow' ('umbra') or a hint of what is to come, as 'ad-' means towards. This helps you remember that 'adumbrative' refers to something that outlines or suggests.
