Dammed Mouth: Tongue Tied

 A river of conscientious thought intends
 to rush unimpeded from my mouth,
 but between my mind and my voice extends
 a dam.  Oh, I can live without

 the dearth of expression that parches my wit
 and the vacuum of language that locks my lip, 
 that not but a dribble of intellect spouts
 despite the flood that wants to pour out!
