  The purpose of this paper is to describe a dictionary geometry <--> algebra
in Lagrangian topology. As a by-product we obtain a tautological (in a sense
explained in the body of the paper) proof of a folklore conjecture (sometimes
attributed to Kontsevich) claiming that the objects and structure of the
derived Fukaya category can be represented through immersed Lagrangians. Our
construction is based on certain Lagrangian cobordism categories endowed with a
structure called "surgery models".
