Just as sadi was obtained from ex by an ico-symmetric diminishing, i.e. chopping off ikepy-caps, tisadi is obtained from tex by an ico-symmetric diminishing, i.e. chopping off iktum-caps.

Much more remarkable is that sadi allows for some of the same operations as regulars do: tisadi is nothing but the truncation operation being applied to it.
