how does speechless say in spanish
what the maenings of speech and less in spanish... and the word together...
speechless : "Sin Palabras" or "Me quedé mudo"
Depending on context speech would usually be some form of Hablar or Decir : e.g. la habla.
Less in Spanish is usually menos, but in the context I believe that you want it, it will be sin (without).
sin decir más=without saying anything further
Do you mean "speechless" as in stunned (dumbfounded)? This new turn of events left him utterly speechless. (sin habla).
