legendo

This word is the best near-collision in the whole language, and it is worth slowing down for. Esperanto has legi, "to read". Esperanto also has the suffix -end-, "which must be done": pagenda is payable, farenda is to be done, legenda is to be read. Put them together and leg-end-a is a real, correct, currently useful Esperanto adjective. So when you meet legendo the parse leg-end-o is not merely tempting, it produces a word that actually exists and means "a thing which must be read".

It is still the wrong parse. Legendo is a single root borrowed whole from Latin, and the story it names does not have to be read by anybody. If you want "a thing that must be read" the Esperanto is legendaĵo, with -aĵ- doing the work of making the adjective into a thing, and the difference of one syllable is the difference between a Reading and King Arthur.

What makes it lovely is that the false seam is not false at all historically. Latin legenda really was legere plus a gerundive ending, and Esperanto's -end- is a deliberate borrowing of that same Latin gerundive. So legendo is a word that was built exactly this way, a thousand years before Esperanto existed, then frozen and imported as a lump. The parse is right about the history and wrong about the grammar, which is the most instructive kind of mistake.

Against its neighbours: a fabelo is a fairy tale, understood by everyone to be invented; a legendo is attached to a real place, person or people and is half believed; historio is what actually happened, or the discipline that studies it. And in the figurative sense the word has travelled the same way as in English, so a great player really can be legendo de la sporto.
