konsekvenco

The seam is real in Latin and dead in Esperanto. Sekvi, to follow, is a live root at rank 150, and kon- looks like it could be kun-, with. So konsekvenco invites the reading that which follows with, and the reading is not even wrong about the history: Latin consequi really is con- plus sequi, and sekvi really does come from the same sequi. What is wrong is the tense. Latin fused those pieces two thousand years before Esperanto existed, and the word arrived here as one indivisible root. This is the inspiri class - a compound that came in already welded shut - and the test is simple: you cannot swap the parts. There is no *konsekvi, and kunsekvo is not a word.

Two senses, and English only kept one. The first is the ordinary one, a consequence, what follows from an act. The second is consistency, of a person or an argument: agi kun konsekvenco is to act consistently, and konsekvenca means logically consistent, self-agreeing, sticking to your principles. English lost that sense of consequence centuries ago but kept it in consequent and consequential; French, German and Polish all still have it, which is why Esperanto does. Watch it in translated prose, because it is easy to read the wrong one.

Against the plain word. Sekvo is the everyday consequence: what came next, no argument implied. Konsekvenco is heavier and more logical - the thing that had to follow. Rezulto is the outcome viewed as an endpoint, and kaŭzi works the chain from the other end. Konsekvence as an adverb means consequently, and it is a useful connector in argument.
