Utterless

Tis true, an adultres cannot be sham’d anough by any publick proceeding; but that woman whose honour is not appeach’t, is lesse injur’d by a silent dismission, being otherwise not illiberally dealth with, then to endure a clamouring debate of utterles things, in a busines of that civil secrecy and difficult discerning, as not to be over-much question’d by neerest friends.

1820, John Keats, Hyperion, Book 2, in Lamia, Isabella, The Eve of St. Agnes, and Other Poems, London: Taylor and Hessey, pp. 173-174, […] there is a noise Among immortals when a God gives sign, With hushing finger, how he means to load His tongue with the full weight of utterless thought, With thunder, and with music, and with pomp:

Thin lines of care about her mouth, And utterless longings in her eyes.
