CONJUNCTIONS. As a conjunctional suffixAs, like "that" (see 287), is used as a conjunctional suffix: sometimes being superfluously added to words that are already conjunctions. In the case of "when as," "where as," it may be explained from a desire to give a relative meaning to words interrogative by nature:
; i. 2. 75. So
“(I am) one that was a woeful looker-on
When as the noble duke of York was slain.
, for "where."
