England slangs? Or dialects?

Not dialect. Not slang. If you want a category name, I suggest "baby-talk". These examples probably invented by JK Rowling.

that's right

neffy being a baby talk, silly way of saying nephew

it is showing what a silly woman she is and how spoilt Dudley (here being called Dudders) is.

Right on. Thank you.

What does "pooh" stand for? Dictionaries tell us "pooh" meaing "Used to express disdain or disbelief." But the speaker spoils Dudley, bot disdaining him.

"pooh" is a funny sort of word.

BE CAREFUL because used on its own it is a euphemism for "****". For example children (and many adults) might say "I want to do a pooh". You try not to step in dog pooh in the street.

"Pooh-pooh" pronounced pupu (noun) means "****"

If someone "pooh-poohs" (verb) an idea or suggestion they are (politely) saying it is worthless (like excrement).

In the baby-talk context referred to, it is sometimes found as a meaningless addition to words for example in the type of infantile speech a parent might use when speaking to to a (very) small child. Often the final 'h' is lost. Thus a teddy bear might become "teddy-poo" or a dog "doggy-poo". There is the famous bear called Winnie The Pooh. Sometimes adults will use it whimsically, or sarcastically to each other to suggest childishness.

It is all to do with toilet training I think...

Excellent reply.
Thank you Contrex.

I wonder what windy-wandy stands for.
Could anyone be so kind to explain it?

You did not read my earlier replies properly. Or you did not understand. These are NOT normal English phrases. Windy-wandy is not an English phrase. Again, I will tell you it was made up by JK Rowling. That is, invented. It may be that windy-wandy means nothing at all.. Wind? Window? Wand? Who can tell? Please give the context. (The sentence and paragraph in which it appears). Maybe a JK Rowling fan will read this.

Contrex, you are spot on with your explanation.

The vast majority of women (obviously JKR has this thing going on) have an inbuilt ability to talk in rhyming nonsense words when confronted with a baby, or very young child.
A man, when confronted with a gurgling baby in a pram will say things like "Oh, he's a fine looking little chap" or "What a beautiful baby, you must be very proud", when truthfully, he's thinking "If that thing starts screaming or going red in the face whilst making grunting noises, I'm outta here".

A woman on the other hand, will bend down so that her nose is almost touching the baby's nose, and suddenly start saying things like " 'oos a widdle cuddly wuddly binky boo boo den? 'Es 'e is, 'e's a widdle man wiv widdle handy pandies an' widdle tootsie wootsies an' kicky wicky legs"

This utter nonsense is accompanied by a rythmic wagging of the head from side to side, whilst the whole intonation of the gabble is made so that it goes up and down in an exaggerated sing song fashion.

The effect of all this baby gabble has not yet been scientifically researched, as far as I am aware. But from an outsiders's (male) point of view, I can say that it normally ends up with the baby screaming blue murder, whilst a crowd of women simultaneously go "Awwwwwww".

"Windy wandy" is, I would imagine, referring to a wand, in this kind of baby gabble.
eg...."Oo's got a widdle windy wandy then?"

Thanks.

Regarding the context, see the beginning episode of the movie Harry Potter And The Prisoner Of Azkaban. Here are some dialogues of the context:

Harry. Harry.



Harry, open the door.



Marge. How lovely to see...



Uncle Vernon,
I need you to sign this form.



What is it?



Nothing. School stuff.



Later perhaps, if you behave.



I will if she does.



- Oh, you're still here, are you?
- Yes.



Don't say yes
in that ungrateful way.



Damn good of my brother
to keep you.



He'd have been straight to an orphanage
if he'd been dumped on my doorstep.



Is that my Dudders?
Is that my little neffy-pooh?



Give us a kiss. Come on. Up, up.



Take Marge's suitcase upstairs.



Okay.



Finish that off for Mommy.
Good boy, Rippy-pooh.



- Can I tempt you, Marge?
- Just a small one.



Excellent nosh, Petunia.



A bit more.



Usually just a fry-up for me,
what with dogs.



Just a bit more. That's a boy.



You wanna try
a little drop of brandy?



A little drop of brandy-brandy
windy-wandy for Rippy-pippy-pooh?



What are you smirking at?



Where did you send the boy,
Vernon?



St. Brutus'. It's a fine
institution for hopeless cases.



Do they use a cane
at St. Brutus', boy?



Oh, yeah.



Yeah. I've been beaten
loads of times.



Excellent. I won't have this
namby-pamby...



...wishy-washy nonsense about
not beating people who deserve it.



You mustn't blame yourself
about how this one turned out.



It's all to do with blood.
Bad blood will out.



What is it the boy's father did,
Petunia?



Nothing. He didn't work.
He was unemployed.



- And a drunk too, no doubt?
- That's a lie.



- What did you say?
- My dad wasn't a drunk.



Don't worry. Don't fuss, Petunia.
I have a very firm grip.



I think it's time you went to bed.



Quiet, Vernon. You, clean it up.



Actually, it's nothing to do
with the father.



It's all to do with the mother.
You see it all the time with dogs.



If something's wrong with the bitch,
then something's wrong with the pup.



Shut up! Shut up!



Right.



Let me tell you...



Vernon!



Vernon! Vernon, do something!



Stop!



I've got you, Marge.
I've got you.



- Hold on, hold on.
- Get off.



- Don't you dare!
- Sorry.



Oh, Vernon.



Oh, God.



Marge!



Please!



Marge!



Come back!



You bring her back!
You bring her back now.



- You put her right!
- No. She deserved what she got.

Well, I am also wanting to know if "namby-pamby...
...wishy-washy" means NOTHING.

===========================
Excellent. I won't have this
namby-pamby...
...wishy-washy nonsense about
not beating people who deserve it.

Mission Accomplished!

See, we were all taking bets who could make the baby scream first, and the "awwwwws" are from the losers.

Ha!

two words used to describe a meek, indecisive and ineffectual person or in this case, behaviour

It has, quite extensively! It's called Motherese. It's great stuff. A recent theory holds that it was the beginning of all language:

Baby talk is also used to show affection between besotted adults. The Dudleys are being romantic--they also want their drinkie-winkies

As Pan noted, "namby pamby" means "effete" and "wishy-washy" "washed out" or "ineffectual".

That's right!

I feel sorry for you sometimes, OristarA, because you always seem to choose the most difficult texts and unsuitable words to puzzle over.

A masochist, one might say, or a 'glutton for punishment'.

Soz, that's amazing!


Are you trying to say that you women are NOT actually trying to make the small pudgy thing cry then?

Today bibble-babble, tomorrow Shakespeare.
