ETYMOLOGY
from Latin dubitabilis, from dubitare (to doubt)
EXAMPLE
“…Has my goodneesse,
Clemency, loue, and fauour gracious rays’d thee
From a condition next to popular labour,
Tooke thee from all the dubitable hazards
Of Fortune her most vnsecure aduentures?
And grafted thee into a branch of honour,
And dost thou fal from the top bough by the rottennes
Of thy alone corruption, like a fruite
That’s ouer-ripned by the beames of fauour,
Let thy owne weight reward thee, I haue forgot thee, …”
From: A Game at Chæss as it was acted nine dayes to gether at the Globe on the banks side
By Thomas Middleton, 1625
