Speechless

Comment 16

In Spanish ''speechless'' means ''sin palabras''. This noun comes from the verb to speak if you add the suffix -less to the noun speech you've got the word 'speechless' which means unable to speak specially as the temporary result of shock or some strong emotion. A word similar to speechless is dumbstruck.
More examples of this style of suffix are careless, cheerless, endless, fearless, hopeless or painless.
I think that a lot of things can leave you speechless as visit to a museum, a song or an advance in technology.
One of the things that left me speechless was visiting the Prado Museum in Madrid. How beautiful!
