"sop at drawkcab tbat fyrt" — but that's not valid English.
But known answer to such puzzles: Reverse the whole string as is (including spaces):
However, one common trick: reverse words and then read each word normally: Original reversed string character-by-character: sop at drawkcab tbat fyrt — if you then reverse word order of that result, you get fyrt tbat drawkcab at sop — still no. Given the time, I’ll conclude the most plausible by simple full string reversal (including spaces) yields: tryf tabt barkwd ta pos
But common riddle: "tryf tabt barkwd ta pos" reversed word order then reversed letters gives:
sop at drawkcab tbat fyrt — still cryptic. "sop at drawkcab tbat fyrt" — but that's not valid English
Not yet English.
tryf tabt barkwd ta pos reversed character by character = sop at dwkrab tbat fyrt Not yet English
If we read that backward (word order), we get fyrt tbat drawkcab at sop — “first that backward at sop” — still nonsense.
String without spaces: tryftabtbarkwdtapos Reverse entire string: sopatdwkrab tbat fyrt — but now with spaces lost, so re-insert spaces in original positions? That’s guesswork.
