§ Common Pitfalls
The word 'ascertain' is a powerful and precise verb, but its formal tone and specific meaning often lead to misuse. Understanding these common mistakes can help you wield 'ascertain' with confidence and accuracy.
§ Mistake 1: Using 'Ascertain' as a Noun
- DEFINITION
- To find out or learn with certainty through examination, investigation, or experimentation. It involves the process of making sure of a fact or situation to eliminate any doubt.
One of the most frequent errors is treating 'ascertain' as a noun. While many verbs can be nominalized (e.g., 'to run' becomes 'a run'), 'ascertain' does not have a direct noun form that means 'the act of ascertaining.' People sometimes try to create phrases like 'an ascertain of facts,' which is grammatically incorrect.
Incorrect: The team made an ascertain of the root cause.
Correct: The team worked to ascertain the root cause.
Correct: The team undertook an investigation to ascertain the root cause.
§ Mistake 2: Using 'Ascertain' When a Simpler Verb Suffices
Because of its formal and precise nature, 'ascertain' can sometimes sound overly academic or stilted when a simpler verb would convey the same meaning more naturally. It implies a deliberate and thorough process of discovery, often involving some degree of effort or investigation.
Less natural: I need to ascertain what time the movie starts.
More natural: I need to find out what time the movie starts.
Appropriate use: The detective worked tirelessly to ascertain the suspect's whereabouts.
§ Mistake 3: Redundancy with 'Certainly' or 'For Certain'
The definition of 'ascertain' already includes the idea of finding out with certainty. Therefore, adding words like 'certainly' or 'for certain' after 'ascertain' creates redundancy and can sound awkward.
Incorrect: We need to ascertain the facts for certain.
Correct: We need to ascertain the facts.
§ Mistake 4: Confusing 'Ascertain' with 'Ensure' or 'Confirm'
While related, 'ascertain,' 'ensure,' and 'confirm' have distinct meanings:
- Ascertain: To discover something with certainty through investigation. It's about finding out.
- Ensure: To make sure that something will happen or be the case. It's about guaranteeing an outcome.
- Confirm: To state or show that something is definitely true or correct. It's about verifying existing information.
Incorrect: Please ascertain that all doors are locked.
Correct: Please ensure that all doors are locked.
Incorrect: The report ascertained the previous findings.
Correct: The report confirmed the previous findings.
§ Mistake 5: Incorrect Preposition Usage
'Ascertain' is typically followed directly by the object of discovery, or by a clause introduced by 'if' or 'whether.' It does not usually take prepositions like 'about' or 'on' when referring to what is being discovered.
Incorrect: We need to ascertain about the new policy.
Correct: We need to ascertain the details of the new policy.
Correct: We need to ascertain whether the new policy applies to us.
By being mindful of these common mistakes, you can use 'ascertain' effectively to convey a precise and formal process of discovery and verification, enhancing the clarity and sophistication of your communication.
§ Similar Words and When to Use 'Ascertain' vs. Alternatives
Understanding the nuances between similar words is crucial for precise communication. While 'ascertain' implies a definite and often rigorous process of discovery, several alternatives offer slightly different shades of meaning. Let's explore them.
§ Ascertain vs. Determine
- DEFINITION
- To establish or conclude something definitively, often after consideration or calculation. 'Determine' can sometimes imply a decision or a cause-and-effect relationship, whereas 'ascertain' focuses solely on discovery.

The committee needed to determine the best course of action.
§ Ascertain vs. Discover
- DEFINITION

§ Ascertain vs. Confirm
- DEFINITION
- To establish the truth or correctness of (something previously believed, suspected, or rumored to be true). 'Confirm' suggests verifying existing information, whereas 'ascertain' is about finding new information or making sure of something for the first time.

§ Ascertain vs. Verify
- DEFINITION
- To make sure or demonstrate that something is true, accurate, or justified. 'Verify' is very similar to 'confirm' in that it involves checking the accuracy or truth of something, often against a standard or fact.
While very close in meaning to 'confirm', 'verify' often implies a more formal or technical process of checking for accuracy. 'Ascertain' remains focused on the initial act of finding out with certainty.

The word "ascertain" is a verb, not a noun. It is often used in formal contexts and implies a systematic effort to discover the truth. It's frequently followed by a 'that' clause or a 'what/when/where/how' clause. For example: 'The detective tried to ascertain **that** the witness was telling the truth.' or 'He is trying to ascertain **what** caused the problem.'
A common mistake is using 'ascertain' when a simpler verb like 'find out' or 'determine' would suffice, making the language sound unnecessarily formal or stilted. Another mistake is using it as a noun; it does not have a noun form. People might incorrectly say things like, 'The ascertain of the facts was difficult,' instead of 'The ascertainment of the facts was difficult' or, more simply, 'Finding out the facts was difficult.' Finally, sometimes people use 'ascertain' when they mean 'confirm' or 'verify,' but 'ascertain' implies a discovery process rather than just checking existing information.
