Confusion about the word 'dhamma'?
Dhamma encompasses sankhara[created] but it also encompases the cessation principle which is not included in sankhara as it is asankhata [not-created].

Both formerly &amp; now, it is only stress that I describe, and the cessation of stress.&quot;sn22.86

There are these famous lines;
 Sabbe sankhara anicca
 Sabbe sankhara dukkha
 Sabbe dhamma anatta

Translated;
 All formations are impermanent
 All formations are suffering
 All Dhamma [teachings] are not-self

Then reconciled with;

Both formerly &amp; now, it is only stress that I describe, and the cessation of stress.&quot;

It makes sense because;

Stress is part of the teaching [things that are taught]
Cessation of stress is part of the teaching [things that are taught]

The semantic referent of #2 is the unconditioned; is neither impermanent[anicca] nor suffering[dukkha]; but it is likewise not-self[anatta].
