Kinda inexact definition in Commad chapter ("reify")

[mtarini]

I skimmed through your book and found it extremely enjoyable. Thank you so much for sharing!

A very minor rephrasing you might want to consider is that when you say...

"Reify", in case you’ve never heard it, means “make real”.

I think it would be, at the same time, more etymologically correct and better for the flow of that paragraph to adopt the definition ...
To reify = make an object out of something, i.e. turn something (abstract) into a (concrete) thing.

"Reify" comes directly from Latin Res, Re (thing, object), so it literally means "objectify", which is exactly what you need one sentence later. True, the adjective "real" comes from the same Latin world, but still. (also note: no letter L in "reify").
