Tarien (v.) - To delay in acting, tarry, procrastinate; be slow to do something; to hinder.
What sholde I tarien al the longe day?
He took the chalk, and shoop it in the wise
Of an ingot, as I shal yow devyse.
I seye, he took out of his owene sleeve
A teyne of silver -- yvele moot he cheeve! --
Which that ne was nat but an ounce of weighte.
- Chaucer, Geoffrey: The Canterbury tales (1387-1394)
