Bn 10 Alyyn Fwrs Dha Rayz Awf Hyks Thmyl [ Editor's Choice ]

Could be a badly typed or transcribed exercise from English:

String:

Maybe "10" is not "th" here but simply "ten". Let’s check: bn 10 alyyn fwrs dha rayz awf hyks thmyl

"alyyn" = all in (a-ll-i-n) but doubled y = just emphasis. Then: Could be a badly typed or transcribed exercise

So: bn = been, 10 = ten, alyyn = all in, fwrs = force, dha = the, rayz = raise, awf = of, hyks = hikes, thmyl = the mile. 10 = ten

Original English: — nonsense. Maybe the intended English: "Bent on all in force, the race of hikes the mile" — still poor.
