Usage Note

Typically appears after linking verbs (be, stand, remain) rather than directly before a noun, though attributive use (e.g. 'a speechless crowd') is possible. When specifying the cause, use at, by, or with: 'speechless at the news', 'speechless with anger'. The intensifiers absolutely, completely, and totally are preferred over very.

Common Mistakes

I was very speechless when I heard the news.
I was completely speechless when I heard the news.
speechless is a non-gradable adjective; use absolutely, completely, or totally instead of very.
I was speechless about his decision.
I was speechless at his decision.
the preposition about is not idiomatic; use at, by, or with to indicate the cause.

Sense: adjective/1

All four describe a reaction to something unexpected, but they differ in tone and implication. Stunned is the broadest — it can describe any kind of shock (good or bad) without necessarily meaning you cannot speak. Dumbfounded carries a stronger sense of bewilderment: you are not just shocked but confused by what happened. Lost for words is an everyday idiom that focuses on the temporary inability to reply, often in polite or emotional situations (e.g. receiving a gift). Flabbergasted is informal and slightly humorous, suggesting the speaker finds the situation almost absurdly surprising. For example: 'The audience was stunned by the final scene'; 'She was dumbfounded by the complexity of the form'; 'He was lost for words when they offered him the job'; 'I was flabbergasted by the price of the tickets.'

Etymology

Old EnglishMiddle EnglishEnglish

Formed in Old English from 'sprǣc' (speech, the act of speaking) plus the suffix '-lēas' (without). The word originally meant simply 'silent, not speaking', and only later took on the specific emotional sense of being struck silent by a powerful feeling. The modern meaning 'unable to speak from astonishment or strong emotion' became dominant by the 19th century.
