> Something that is inspired by something is also based on that thing.

Inspire -- give rise to -- stimulate, motivate, spawn, engender.

Based on -- rooted in -- built upon, be founded on/upon, be anchored in something, rooted in.

A hamburger inspired the design of the Millenium Falcon, the ship is not based on hamburgers. A comic book inspired the movie 300, which is only loosely based on the comic and historical fact.

A story that is based on specific events it must build upon those events. A story that is inspired by something has no presumption of content, only that some facet of it motivated the storyteller somehow.

In both those examples the thing is “rooted in” the item/thing you mention.

So while, yes there is nuance, they still broadly mean the same thing: you actually just gave two examples agreeing with me.

Nope.

And directly conflicting definitions are not "nuance". You are missing a qualifier in order to make the point you think you're making (ie "the design of X is rooted in..."). You've also wilfully read past both examples in order to stretch this point.

Inspiration can not be understood as "rooted in". That is not how words or sentences work. The millenium falcon is not rooted in Hamburgers. "Imagine" is not rooted in Yoko Ono.
