tajloro

Another -or- fossil. Esperanto makes an agent noun with -ist- for a trade and -ul- for a person characterised by something, and it has no -or- suffix whatsoever. So tajloro does not divide into tajl- plus an ending: there is no root tajl- in the language to divide it into. The word arrived whole with its French morphology intact, exactly like ambasadoro, motoro, doktoro and profesoro. When a root ends in -oro and refuses to come apart, this is nearly always the reason.

The proof, as usual, is in the shop. If -or- were live here, the workshop would be tajlejo. It is tajlorejo, -ej- bolted onto the whole undivided root, and the verb built off the trade is tajlori, to tailor. The language tells you where its own seams are if you watch what it does with them.

The trade's actual verb is a different word.Kudri is to sew, and it sits two hundred and fifty ranks higher up the list than this word, because everybody sews and only some people tailor. A tajloro cuts and fits: they work with ŝtofo, makes a kostumo, and mezuras before he touches the scissors. Kudristo is a plainer word for somebody who sews for a living, tajloro the one with the reputation.
