Usage tips
Word structure
The word is made up of 'Sprache' (language/speech) and the ending '-los' (-less). The ending '-los' means 'without,' so 'sprachlos' literally means 'without speech.'
EXAMPLE
Als er die Rechnung sah, war er für einen Moment sprachlos.
When he saw the bill, he was speechless for a moment.
Sentence structure
'Sprachlos' is often used as a predicative adjective with the verbs 'sein' (to be), 'werden' (to become), or 'machen' (to make). It describes a person's state.
EXAMPLE
Ihre unhöfliche Antwort machte mich einfach sprachlos.
Her rude answer simply left me speechless.
Typical collocations
To state the reason for being speechless, German often uses the preposition 'vor' with a noun in the dative. Typical combinations are 'sprachlos vor Wut' (speechless with anger), 'vor Schreck' (with fright), or 'vor Erstaunen' (with amazement).
EXAMPLE
Sie war sprachlos vor Staunen, als sie das Panorama sah.
She was speechless with amazement when she saw the panorama.

sprachlos vs platt
flat / exhausted
'platt' and 'sprachlos' can both describe someone being unable to say anything because of surprise. 'sprachlos' says directly that someone temporarily cannot find the words, for example because of shock, amazement, or anger. 'platt' is more colloquial and emphasizes more that someone is very surprised or completely impressed. 'sprachlos' is more neutral and more precise when the inability to speak is really important. 'platt' fits better in casual conversations when you want to express strong amazement.
sprachlos
Als Tom das Geschenk sah, stand er sprachlos im Wohnzimmer.
When Tom saw the gift, he stood speechless in the living room.
platt
Nach der Nachricht war sie erst einmal völlig platt.
After the news, she was completely stunned at first.
