But if you can do this with communication or communal, you you can do the same with aerodrome (146) (206), dromedary (206) and hippodrome (206). The first is the house and runway of an aeroplane (146) or dirigible (185), i.e. controlled (185) airship with gas (796) bag, usually filled with helium (646), an element first known to exist because of its lines in the sun's spectrum (662). A dromedary (206) is a first-rate runner. A hippodrome is a place where horses run around for the diversion of harassed hedonists (131). Hippo- is not on the word-list. We use the Latin root of the zoological (630) (289) genus (18) present in equine (578), or (even worse) equitation (578); but since we have now tamed hippo- we may as well use it for the next stage of our itinerary (273). This is a visit (457) to Mesopotamia (92) (659) by way of Hippopotamus (659). Thence we can proceed with a confessedly (183) anterior (77) motive but retrogressive (97) motion (476), to the Mesozoic (92) (630) age. Our course (206) is then clear. Here are specimens (424) to demonstrate (199) how we can pair off words with common international roots:

To get the best out of the detective (467) method (302), we can put everyday words in contraposition (80) to more exotic ones with a common root, e.g. neuralgia (525) (148) and analgesic (525). Among everyday words which are self-
