One way to learn EmacsLisp is to compare it with other languages that you might already know. This page lists some comparisons.
From AlanJPerlis?’ foreword to the Wizard Book (Wiki:StructureAndInterpretationOfComputerPrograms): Pascal is for building pyramids – imposing, breathtaking, static structures built by armies pushing heavy blocks into place. Lisp is for building organisms – imposing, breathtaking, dynamic structures built by squads fitting fluctuating myriads of simpler organisms into place. The organizing principles used are the same in both cases, except for one extraordinarily important difference: The discretionary exportable functionality entrusted to the individual Lisp programmer is more than an order of magnitude greater than that to be found within Pascal enterprises. Lisp programs inflate libraries with functions whose utility transcends the application that produced them. […] As a result the pyramid must stand unchanged for a millennium; the organism must evolve or perish.
