Let's try reversing the whole string before splitting: klmat-aghnyh-sdam-yabw-aday reversed = yada-wbay-mads-hynhga-tamlk — still "yada" and "mads" appear but not fully clear.
"klmat" — maybe "format" with each letter shifted? k→f (-5), l→o (+3), not consistent.
This looks like a coded or scrambled phrase. Let me try to see if it's a simple substitution or rearrangement.
