Answer

Wa alaikum assalaam wa rahmatullahi wa barakatuh,
A sukoon is the absence of a vowel.  When we stop on a word, we stop with a sukoon on the last letter.    A pure sukoon or is a sukoon free of  or .  In other words, it is a plain sukoon (absense of a vowel) on a sukoon or put on a letter that had a vowel   This term cannot be used on words that have a tanween fath or medd letters.
