One of the most direct terms you can use in referring to a person who complains is ‘Nagger’.

According to the Oxford Dictionary, a ‘Nagger’ is ‘someone who continuously reminds or complains to (someone) in an annoying way, often about insignificant or unnecessary matters.’ A shorter definition is ‘Someone who nags’

You can call a person a nagger;

  • If he/she is complaining about a situation that doesn’t concern you or that you can’t fix. He/she just keeps ranting about it, especially at a later or unexpected moment. Such a person is complaining needlessly and purposelessly.
  • If he/she always has something to complain about concerning something e.g. workplace, siblings, etc. While there are similar words that are more particular about this kind of complaining, you can still refer to such a person as a nagger.
  • If he/she complains endlessly about a situation that has been fixed or cannot be fixed by anyone. In this case, there is nothing more that can be done about the situation and he/she is just reflecting on how annoying the situation had been.

Here is an example of how to use ‘Nagger’ in a sentence;

  • Don’t think I’m just being a nagger. He has provided a solution but I just needed to tell someone how I really feel about what happened.


When referring to a person who always finds the tiniest or barely noticeable things to complain about, you can call him/her a nagger.

According to the Oxford Dictionary, a ‘faultfinder’ is simply ‘a person who finds faults’. ‘Finding faults’ can be defined as the act of criticizing something or someone excessively.

Faultfinding is when you seem to be consciously looking for something to complain about or a reason to condemn something or someone.

However, the word is an ‘accusation’ for people who seem to always have something to complain about or are difficult to please.

You can call a person a fault-finder:

  • If he/she complains about something that would otherwise not be noticed by anyone. He/she may seem to be consciously looking for a reason to call you incompetent.
  • If he/she calls out flaws that can be ignored or that are not actually important. He/she may also find different faults at different times, asking that a project be redone several times.

A faultfinder will be difficult to satisfy if he/she doesn’t believe that another person can be perfect or satisfy him/her.

Here is an example of how to use ‘Faultfinder’ in a sentence;

  • My boss is the worst faultfinder ever so I’m glad he doesn’t have to be impressed with my work. Trying is a waste of time.

What do you call a person who complains about everything


When referring to a person who complains about himself and others while seeking perfection, you can call him/her a perfectionist.

A perfectionist may find it difficult to stop complaining due to the desire for a high standard that even he/she can hardly picture.

According to the Oxford Dictionary, a Perfectionist is a person who is unwilling to accept anything that is not perfect or does not meet very high standards’. Most Perfectionists have their ideas of perfection and want everything done exactly as they picture it.

Being perfectionistic is being choosy with what you accept from others or yourself. A Perfectionist can be hard on others and equally as hard on himself or herself.

A Perfectionist;

  • Sets a very high standard for himself or herself or others and will complain if the standard is not met. He/she will demand a redo till it’s made exactly as he/she expects. Also, he/she will find faults with every part that doesn’t match or isn’t better than what he/she wants.
  • Wants perfection to be proven. He/she isn’t just hard to please but can be convinced to change his/her perception of perfection with irrefutable proof. Till that is done, a Perfectionist will complain about anything that is contrary to his/her ‘perfect’ ideas.

Here is an example of how to use ‘Perfectionist’ in a sentence;

  • Don’t take me for a Perfectionist. We are going against opponents who meet tremendously high standards.


Here is a word for a nagger who complains under his/her breath. This can refer to virtually anyone who complains but it’s more appropriate if he/she is not directly talking to anyone or is inaudible.

According to the Oxford Dictionary, a Grumbler is simply ‘someone who persistently grumbles’. Grumbling is the low, growling sound often made by some animals. In this context, it refers to ill-natured complaints in a low voice and surly manner.

A Grumbler complains under his/her breath without confronting or referring to anyone. While his/her voice may be barely audible, the murmurings are loud enough for anyone to know that he/she is making a sound.

Here is an example of how to use ‘Grumbler’ in a sentence;

  • He’s a Grumbler when it comes to food and he still hasn’t learned to cook.


If you are dealing with a person who is stubborn about details and will complain if not given specifically what he/she demands, you can refer to him/her as ‘Finicky’.

According to the Oxford Dictionary, a Finicky person is ‘someone who is very choosy and difficult to please.’ Another definition is ‘a person who is particular about petty details’.

A finicky person;

  • has an idea of what he/she desires in mind and wants to be given exactly that. He/she demands to be satisfied and will not accept anything that doesn’t match what he/she desires.
  • is obsessed with his/her choice and doesn’t care about what is better (unlike a Perfectionist).
  • may also be obsessed with tiny and ignorable details, wanting everything to perfectly match his/her example. He/she may give guidelines and want every one of them to be followed without any change.

Here is an example of how to use ‘Finicky’ in a sentence;

  • The teacher is extremely finicky so you should keep your ideas to yourself if you want to pass this subject.
