What would you call someone who often changes his mind, her behaviour or vice versa, (2025)

Hi,

How would you call someone who often change his behaviour . I mean from day to another she's quite moody ! How would you call this person who always change her mind ?

Thank you,

Claude.

Hi Claude.

You could call her 'temperamental', 'moody', 'unpredictable'.

If she's always changing her mind she could be 'indecisive', 'uncertain', 'undecided'.

There are many more adjectives.

You could simply say, 'She's a woman!'

Ouch, la reine victoria! Claude, you could also say that she has unpredictable mood swings.

But we're not talking about changes in mood - but rather, those who change their mind often.

There is a difference between the two.

More adjectives, generally though of as feminine: Tempestuous, Petulant, capricious, flaky, fickle, flighty

And some masculine equivalents: Mercurial, eccentric.

And universally: Volatile, temperamental, impulsive

And for someone who changes for purposes of fitting in or getting along: A

chameleon.

The questioner asks about both.

And for someone who changes for purposes of fitting in or getting along: a cameleon.

Except for "chameleon" and "mercurial," I don't really think any of these work.

"Tempestuous" to me means "violent, turbulent, stormy."
"Petulant" means "irritable, peevish, irascible."
"Eccentric" means "strange, peculiar, unorthodox."
"Volatile" means "prone to violence, explosive."

None of the above necessarily refers to someone who changes his mind a lot.

Inconsistent

behaviour.

Oops - I misread the question. I thought she was answering her own question by saying that one who changes his behavior is "moody" (which I think works fine) as a pretext before asking the follow-up question about someone who changes his mind a lot.

"Tempestuous" to me means "violent, turbulent, stormy."
People who live violent, turbulent, stormy lives, generally do so because they change the minds and their moods frequently, rather a lot like the weather.

"Petulant" means "irritable, peevish, irascible."
People who are peevish tend to be "contrarian", which tends to cause them to change their minds a lot so as to remain contrary.

"Eccentric" means "strange, peculiar, unorthodox."
Hmm. Maybe. And yet most "eccentric" men are seen as somewhat capricious, no?

"Volatile" means "prone to violence, explosive."
See, tempestuous above.

In various contexts, in various ways, each of those words may be fitting for a highly variable person. Of course, they have to be applied appropriately to the context and people involved.

Whimsical, if you wish to be lighthearted.
Devious, if you wish to go towards the other end of the spectrum.

(Incidentally, I see from the original post that this person also changed his sex.
And while I'm being incidental, I didn't know of cameleon as an alternative to chameleon until today.)

Streaking , gloomy or sullen ! I think they are close (?) you can use moody it would be my choice to describe a person who changes his mood very often.

Sorry to disagree Mr Blue.

gloomy or sullen refer to a person's mood at a given point in time, not to the fact that they are always behaving differently from one day to the next.

Is 'streaking' an Australianism? I've never heard it used in the UK, apart from running naked across rugby pitches, etc.

Agreed. I was just being skeptical because I didn't think that the words on their own referred to the person's variability (cf. "mercurial" and "chameleon").

Also, as you'll notice in post #10, I had misunderstood the question to be exclusively referring to those who change their mind as opposed to those who change their mood. Including moodswings does put a different spin on things.

I didn't either! (headed off to edit yet again.......)

Ah...I like "fickle"! I think it was on the tip of my tongue - well done, Rsweet!

Another word that comes to mind is "vacillate," which, albeit not an adjective, works as well.

"How would you call someone who often change his behaviour . I mean from day to another she's quite moody ! How would you call this person who always change her mind ?"

I wouldn't call her at all.

Serendipity brings up a good point, Claude. In any European language with which I have a slight familiarity, "How" is often used where an English speaker would say "What." Pardon the lack of punctuation, but "Comment s'appelle," "Como se llama," or "Wie heisst," but in English "What (and not 'how') is it called."

Agreed CAMullen.

Claude should have said 'How would you describe' not 'how would you call'.

I think Surendipity was giving a 'tongue-in-cheek' answer. Not worth bothering with such a girl.

We can even call her capricious.

The word you are "all" looking for is "fickle".
