The Book of Jargon does one thing completely: it defines the working vocabulary of dealmaking, from LOI and QoE through baskets, caps, collars and working-capital pegs, in plain entries written by practitioners, covering corporate and sponsor terminology across a dozen jurisdictions. It is a glossary, and it does not pretend to be more.
The Institute’s reading: language asymmetry is negotiating asymmetry. An owner who has to guess what a term means concedes ground invisibly, and the professionals across the table have no incentive to slow down. This Institute’s standing advice is to never let vocabulary decide a deal point, and this free resource is the fastest cure. Read entries the night before meetings the way Lajoux’s reference is read the night before deal phases.
