usden't to

There is no such word as usedn't. That's an attempt to make a contraction out of a word that can't be made.

"I used to not like it very much, though I majored in it."

or

"I used to not like it very much, while I majored in it."

When in doubt about a word choice why not use a dictionary or spell-checker that's built into MS Word or any text editing program? In fact, there is one (spellchecker) here on A2K that would have caught this.

If you hear someone say the word you are questioning, it sounds like what you spelled. But, what they are saying is "used to didn't." That is not proper English, as Ragman pointed out. But, it is the way some people speak.

It is similar to hearing someone say "ja eat?" What they are saying is "Did you eat?"

Or, "Smore?", which is really "Do you want some more?"

Some people speak words that do not represent proper English, so keep this in mind if you hear rather than see a word. Sometimes it is slang or dialect.

The question was caused by one of my dict. (Modern Chinese-English Dictionary). "usedn't" appears in it.

But, yes, WORD suggests it's wrong.

So that dict. is wrong. right?

"nern" = yeah, I'll have another one

Thank you guys!

Now my question becomes:

Should it be "didn't use to like" or "used not to like", or "used to not like"?

Thanks for your further comments!

As I wrote before it should be "I used to not like it"

or

also acceptable is "didn't used to like it"

Thank you Gagman!
I think I've got it with your comments.

Best Regards!

hmm Gagman? I like that..maybe I'll change my name.

Good luck. You're doing fine.

I've seen "usedn't" in old British children's books, but I never see it being used anymore.

Get adda here

Since "did" is past tense:

"I didn't like such-and-such, although I majored in it."

conveys the meaning without extra, unnecessary words.

Well, gosh, I have so!!

I'll get back to you in a few years when I've gone through all my old books and found one to prove it to you...
