No word in English does not convey all the shades of the word “melancholy”. In its greatest depth and painfulness is the feeling of great spiritual suffering without any particular reason. At a less painful level – the unclear pain of the soul, the passionate desire in the absence of the object of desire, painful languor, vague anxiety, mental suffering, a strong desire. In some cases this may be the desire of someone or something specific, nostalgia, loving longing. At the lowest level, anguish passes into ennui, boredom.
