You may recall how WI 4.16: Names Made in Assembly tells us that given:
--
A color is a kind of value.
Liking relates one person to one color.
The verb to like means the liking relation.
--
one can use either of these:
--
A person (called its fan) likes every color.
Every person likes a color (called his favorite color).
--
This construction directs #inform7 to *create* a thing as a side effect of creating another thing on a 1:1 basis.
Assuming red, green, blue are colors and the people are Alice, Bob, and the ubiquitous yourself, one of them results in the creation of people called red's fan, green's fan, and blue's fan, and one of them results in the creation of colors called Alice's favorite color, Bob's favorite color, your favorite color.
Inform does not reduce, reuse, recycle here: even if there are enough already enough people or colors to go around, assembly always makes brand new ones.
"every" can occur on either side of the verb, and it's the kind of value labeled with "every" whose existence must be independently asserted and the kinds of value on the other side that get created. This is easy enough to remember *if* you already remember the syntax exactly.
The side with a notation about how they should be named is the side that gets created. But I still struggled until something I thought of the other day made it click.
Imagine this relation and verb:
Assembly relates one thing to one thing.
The verb to assemble means the assembly relation.
With that, I find these pretty clear:
Every person assembles a color.
A person is assembled by every color.
And while one *can* define and use that relation and verb, you don't even have to! Just imagining it is good enough for mnemonic value.
