Etymology
The word 'retrospectively' is built on the Latin foundations of retro- (backwards) and specere (to look). The core concept is literally "to look back." This literal sense evolved into the abstract meaning of reviewing or considering past events. The adjectival suffix '-ive' was added to form 'retrospective,' meaning "looking back" or "concerned with the past." Finally, the adverbial suffix '-ly' was appended to create the form describing the manner of an action—in this case, performing an action in a way that involves looking back. Thus, the word's logic perfectly maps its ancient components to its modern usage: acting with a backward-looking perspective.
Analysis

It functions as a bound root conveying the core action of seeing or observing. ively: A modern English adverbial suffix derived from the adjectival suffix '-ive' combined with '-ly', indicating the manner of an action.
