Languages develop and new words are invented. Sometimes they are imported from other languages and sometimes they are made up just because there is a need for them. In this list I have some words I think should be included in Swedish and English. When a word has green background it means this word already exists in that language. When a word has red background it means this word does not exist in that language yet.

Model (verb)

Pastor (verb)

Nader (verb)
Neidra
If there is an election or a poll and candidate a and b are alike each other they will probably nader each other which means some people vote for candidate a and some vote for candidate b. Even if candidate a and b got more votes together than candidate c (and candidate c is really different from a and b) candidate c will still win.
Frame (verb)
Freima

Stalker
Stalkare
Someone who follows a person (often an ex-girlfriend or a celebrity) against his or her will, and refuses to leave the person alone.
Slork
Slork
The word slork is used the same way as the word "and" but it binds the two things together more than "and" does. Example: If you give money to Amnesty and do volunteer work for them those things are connected. If you work for Amnesty and go to the gym these things are not connected. One can say "I give money to Amnesty slork work for them for free, and I am a member of a church slork attend it twice a week." You could also use it when giving hypothetical questions,like "But if you try to rob the bank slork they refuse to give you money slork you show them you have a gun slork they still will not give you money, would you shoot?" You could also use the word slork if two words mean more or less the same thing, but you have to use both anyway. Example: "We send our newsletter for free to psychiatrics, priests slork pastors, teachers and MP."
Bleek
Bläka
The word comes from the Esperanto-word "bleki." It means to be an animal and say what that animal say. It is a word for bark and miaow and bleat and all the other animal-sounds.
heigh
heta
The word means "be called." Example:"I heigh Mary." This is a word which actually has existed in the English language earlier. One can find it in Canterbury Tales. It still exists in for example Swedish (heta) and German (heissen). But for some reason the English-speakers forgot this really handy word.
Pressletter
Insändare
In Swedish newspapers they have a page (or more) to which anyone can send letters about anything in public debate, and it is published in this page. This is called insändare in Swedish. In English one can say pressletter.
Scale-master
Vågmästare
If the right-wing and the left-wing in a parliament have almost exactly the same number of MPs, but none of them have 50% slork there is a party which is somewhere in between right and left, they are scale-masters because they can support the left-wing in some question and the right-wing in other questions, and that way always get what they want.
Lagom
Lagom
Not too much and not too little. Not too hot and not too cold. And so on. Between the extremes and therefore exactly what is best.
Eviljoy
Skadeglädje
The feeling of happiness when something bad happens to someone else.
Prig
Prigg
This is not a common word in English, but it is used sometimes in British English. It means someone who thinks it is really important that everything is dignified and appropriate, and who takes this principle too far.
PC-prig
PK-prigg
The same as a prig, but instead of being eager to protect dignity he or she is eager to protect political correctness. A PC-prig is someone who says things like "You cannot say Indians. One says native Americans. And why do you assume it was to her boyfriend? Maybe she has a girlfriend and not a boyfriend. You can not know that."
Horror example
Skräckexempel
An example of how one should not do.
Humbug
Humbug
Attempts of getting attention or money by lying to people. For example fake photos of Bigfoot.
Wir
Wir
The same as "we," but you stress the fact that you do not include the person(s) you are talking to. Example: If a chief talks to his employees and tell them what the firm will do the next month he says "we" because the employees will have to work with that project. If the chief tells them that he or she will go to another country with his family, he or she says "Wir will go to another country.",
Overhear
Överhöra
Accidently hear what someone is saying to someone else.
Turtle play
Sköldpaddspjäs
A film or play (on a theatre) which is not exciting or fun or touching or educational or anything else. It is so lousy so you could as well just listen to someone who repeats the phrase "Turtles one can joke about, but tragic marriages are nothing to joke about" for two hours.
Violencesnuggle
Våldshångla
The Swedish word for "rape" is "våldta" which means "violencetake." If a guy does not go so far that he rapes a girl, but only hold her tight and forces her to hug and kiss him he violencesnuggles her.
Fewest
Färst
In Swedish one can say "få" for "few," "färre" for "fewer," but not "färst" for "fewest." One should be allowed to do that.
Same-timey
Samtidigt
At the same time.
Charybdise
Karybdisera
To go from Scylla to Charybdis. Example: You have been really lazy all your life, and you must change your behaviour. You go to far and work too hard, instead of being lagom.
