Depression, most people know, used to be termed “melancholia”… Melancholia would still appear to be a far more apt and evocative word for the blacker forms of the disorder, but it was usurped by a noun with a bland tonality and lacking any magisterial presence, used indifferently to describe an economic decline or a rut in the ground, a true wimp of a word for such a major illness …

The Swiss-born psychiatrist Adolf Meyer had a tin ear for the finer rhythms of English and therefore was unaware of the semantic damage he had inflicted by offering “depression” as a descriptive noun for such a dreadful and raging disease. Nonetheless, for over seventy-five years the word has slithered innocuously through the language like a slug, leaving little trace of its intrinsic malevolence and preventing, by its very insipidity, a general awareness of the horrible intensity of the disease when out of control.
