proklami

The seam is a false one, and this page has a precedent. The word invites a split into pro- plus klami, and both halves fail. Pro is a preposition meaning because of; it is not a productive prefix, and pro- attached to a root builds nothing in Esperanto. Klami is worse: there is no such verb, and klamo is not a word in the language and never has been. The reklamo page makes exactly the same point from the other side, and the two words are worth learning as a pair: same Latin verb, two Esperanto roots, neither of them divisible.

What Latin did with it. Clamare is to shout. Pro- sends the shouting forwards, out into the open, and proclamare is what a herald does in the marketplace. That gives proclaim, and the same verb with different prefixes gives exclaim, acclaim, reclaim and declaim. Knowing it fixes the meaning in your memory; it gives you no rule you can apply inside Esperanto, which is the honest position with most international roots.

Three verbs, three registers. Anonci is to announce - a train, a birth, a decision - and is the neutral everyday word. Deklari is to declare, and carries the sense of stating something formally and on the record: deklari militon, deklari sian enspezon. Proklami is grander than both. It is what is done with a republic, a king, a general amnesty or a winner, from a platform and in public. Using it about a train timetable is a joke, and a usable one.

Around the root. Proklamo is the proclamation itself, the document or the speech; proklamado the act of proclaiming; proklamanto the herald. The construction in the third example is worth copying: proklami iun io - to proclaim somebody something - keeps the second noun in the nominative, because it is a predicate and not a second object.
