Yes, ‘admittingly’ is a word, but it is not commonly used in standard English. It is an adverb that means ‘in a manner that admits or acknowledges something.’ However, it is often considered nonstandard or informal.
For example, you might say: ‘Admittingly, I was wrong about the meeting time.’ In this sentence, ‘admittingly’ is used to acknowledge a mistake.
While ‘admittingly’ can be understood, it is more common to use ‘admittedly’ in formal writing. ‘Admittedly’ is the standard form and is widely accepted in both spoken and written English.
Example: ‘Admittedly, I was wrong about the meeting time.’ This sentence conveys the same meaning but uses the more accepted form.
In summary, while ‘admittingly’ is a word, it is better to use ‘admittedly’ in most contexts to ensure clarity and correctness.
