Almost laughable is the complete clue for the word.
Knight also has three letters.
And a synonym for sweat.

You mean an abbreviation of knight has 3 letters?
There are several abbreviations for knight.
When I started the thread, it was with an idea for amusement, i.e. solvable clues, not as a competition as to who could make the most obscure clues.
Requiring a homophone of a word, when none was indicated, then an abbreviation (of which there are several) of that homophone, added to another synonym for another noun to form an anagram, is reaching the extremity of obscurity.
@Justin Passing
All abbreviations of knight must have either a 'K' or an 'N'.
4 letter synonym for sweat:
Horses sweat, men perspire, and ladies gently glow.
glow + kni (or Knt, Ngt, or KCB)
"knowing" = 2 'n's and no 'l'.
