/ the ache / toská: No single word in English renders all the shades of toská. At its deepest and most painful, it is a sensation of great spiritual anguish, often without any specific cause. At less morbid levels it is a dull ache of the soul, a longing with nothing to long for, a sick pining, a vague restlessness, mental throes, yearning. In particular cases it may be the desire for somebody or something specific, nostalgia, lovesickness. At the lowest level it grades into ennui, boredom, skuka. The adjective tosklivïy is translatable as "dismal," "dreary."
