lament

Speechlessness: that is the great sorrow of nature (and for the sake of her redemption the life and language of man -- not only, as is supposed, of the poet -- are in nature) ... Lament, however, is the most undifferentiated, impotent expression of language; it contains scarcely more than the sensuous breath; and even where there is only a rustling of plants, in it there is always a lament. Because she is mute, she mourns.

-- Walter Benjamin Illuminations
