Note 13 — Old Stories

Aigasa, a fantastic term compounded from the verb au, "to accord," "to harmonize," and the noun kasa, "an umbrella." It signifies one umbrella used by two persons—especially lovers: an umbrella-of-loving-accord. To understand the wife's anxiety about being seen walking with her husband under the borrowed umbrella, the reader must know that it is not yet considered decorous for wife and husband even to walk side by side in public. A newly wedded pair, using a single umbrella in this way, would be particularly liable to have jests made at their expense—jests that might prove trying to the nerves of a timid bride.
