spoken

Here are examples of exclamatory sentences starting with “What”. They express strong emotions or feelings.
“What” is a predeterminer that precedes the indefinite article “a”.
The phrases following “What a” are noun phrases, often modified by adjectives for emphasis (e.g., “great”, “wonderful”).
Many sentences are followed by adverbial phrases (e.g., “to save time”, “to be alive”) that provide more information about the noun.
These sentences are common in spoken English to convey strong feelings. They’re less common in formal written English but might appear in dialogue or informal writing.
In the English Grammar Profile, such usage of ‘What’ falls under A2 level for expressing strong opinions.
The most common collocates in corpora are words like “great”, “waste”, “idea”, etc., often followed by infinitive phrases or prepositional phrases acting as adverbs.
This structure allows for a wide range of expressions, from surprise (“What a surprise!”) to disappointment (“What a waste of money!”) to admiration (“What a great idea for a party!”). It’s a versatile and expressive part of English grammar.
