Why this term exists
Some relations gain strength by convergence: repeated paths, reinforcing context, attention and compatible structure accumulate around a node or idea. Attraction names this concentrating side of the relation.
Definition in the system
Attraction is one mode of semonic force, not the whole of relation. It can describe the way attention gathers, the way context makes one candidate increasingly salient, or the way multiple paths reinforce a common structure.
In Serbian the project uses the image pri-vlačna: fibres of meaning being drawn toward one another. This is an operational metaphor, not an etymological proof and not automatically a literal physical force.
Attraction becomes useful only when paired with its limits. A system that only pulls can over-compress, overfit or lose the spacing required for interpretation and adaptation. This is why Detraction is a necessary companion concept.
Example
A term repeatedly reached through independent, context-preserving paths can become a stronger conceptual attractor without becoming more true merely because it is prominent.
