is from a Greek word meaning,

"...no doubt, perhaps, so be, then, therefore, truly, wherefore."

Abingdon's Strong's Exhaustive
Concordance of the Bible  
...That they should seek the Lord,
if haply they might feel after Him, and find Him, though He be not far from everyone of us: for in Him we live, and move, and have our being; as certain also of your own poets have said, 
For we are also His offspring.

Acts 17:27-28
