Definition of "perplext"

By spleen, religion, all we know; That should enlighten here below, Is veiled in darkness, and perplext With anxious doubts, with endless scruples vext And some restraint imply'd from each perverted text; Whilst touch not, taste not what is freely given, Is but thy niggard voice disgracing bounteous Heaven.

1753, Theophilus Cibber, The Lives of the Poets of Great Britain and Ireland (1753)‎

Twas but in a sort I blam'd thee; None e'er prosper'd who defam'd thee; Irony all, and feign'd abuse, Such as perplext lovers use

1805, Charles Lamb, Farewell to Tobacco‎

What might she mean by that? his large black eyes, Yet larger through his leanness, dwelt upon her, Till all her heart's sad secret blazed itself In the heart's colours on her simple face; And Lancelot looked and was perplext in mind, And being weak in body said no more; But did not love the colour; woman's love, Save one, he not regarded, and so turned Sighing, and feigned a sleep until he slept.

1874, Alfred, Lord Tennyson, Idylls of the King‎
