intervjuo

The seam you can see here is not a seam. Inter- is a real and busy Esperanto element - inter is a preposition in its own right, and it builds interparoli, interŝanĝi, internacia - so the eye splits this word as inter plus vjuo and waits for vjuo to mean something. It never does. There is no such root. Intervju- arrived in one piece from English, and it is the English word that contains the Latin inter, several centuries and one language earlier.

You can tell by the shape of it. Vj is not a cluster Esperanto builds; the language's own roots keep their consonants comfortable, and the only reason this one is awkward is that we are looking at a photocopy of an English spelling. Compare intervidiĝi, to meet face to face, which is assembled from Esperanto parts and looks like it.

The family works normally once the root is in place. Intervjui is to interview someone, intervjuanto is the one asking and intervjuato the one being asked - the participial nominals doing what they always do, sorting out who is on which end of the verb.
