4.6: Ich tu dir nichts

In this lesson we are given the conjugation of "tun"  which starts with "Ich tue", but in the examples we have "Ich tu dir nichts" which is translated I won't hurt you. 

Is that an error or an alternate form of 1st personal singular?

Yes, in the first person singular it is common to omit the final "e" in spoken German.

I notice that they have used the literal button here, they might have put something about the missing "e" there.

Thanks for that!
I suspected as much as the lady pronounces it as "tu" whereas the "e" is definitely pronounced earlier when it is conjugated.  But I had a quick look at various other sites and didn't see anything to confirm it.

I'll see whether German with Jenny or Anja has anything to say.

It is not easy to find stuff about it with google, I  did find this:
https://german.stackexchange.com/questions/3901/when-do-we-omit-the-trailing-e-in-1st-person-singular?rq=1

My grammar book comments that the trailing e is often dropped in spoken German and when it is done in written German it will often have an apostrophe to indicate the e was dropped. 
e.g. tu' from your phrase.

Hi Peter--252 and sfpugh,

both "ich tu" and "ich tue" are grammatically correct. I agree with sfpugh, it is very common to drop the "e" in  colloquial speech as well as informal written language.

An apostrophe is usually only used when the shortened word would be ambiguous and hard to read without it.
Some examples would be:
"So ’n Quatsch!" (So ein Quatsch!) - "What nonsense!"
"Die Katze sitzt auf’m Tisch." (Die Katze sitzt auf dem Tisch.) - "The cat is sitting on the table."
"Ich zweifl' daran." (Ich zweifle daran.) - "I'm in doubt about it."
"Ich wohne in D’dorf." (Ich wohne in Düsseldorf.) - "I live in Düsseldorf."

I hope this clears things up!

Viele Grüße

Hi Julia
Although the apostrophe is not necessary in this situation, do you think it would be useful to put one in as a teaching exercise to show what is going on?

Thanks both!
I know that there are lots of elisions & glidings in French, but was less sure as to how much there is in German.

These replies are very informative, and I think sfpugh has a point, it might be useful to have a comment in the lesson.

Hi Peter--252 and sfpugh,

Glad I could help! There is actually a small comment regarding tu as being an alternate form of tue in the lesson. It can be found under "TUN 'To Do' Singular Forms".

As to the apostrophe, I wouldn't recommend putting one in as it would be quite uncommon in this particular case.

Hi Julia,

Thanks again!  Yes I saw that comment now you've pointed it out.
That'll teach me to read the text more thoroughly :).
