'Herumhängen' requires contracted spelling. In any case, I'm not convinced that the proposed pair is a good match. 'Herumhängen' means idling, being lazy whereas 'to hover' is active, even nervous. Therefore: not supported.

@s1chmitt: Please quote several reliable references in both languages for your proposals as required by the submission form.

LEO:
to hover (also) [aviat.] - schweben
to hover - in der Luft schweben
to hover above sth. - über etw.[Dat.] schweben

Siehe auch: to hover
Siehe auch: Hover much?
Siehe auch: to hover - sich herumtreiben, herumlungern
Siehe auch: he doesn't hover

Still, LEO is still completely missing this sense of the verb 'hover,' and it's very common, so it needs to be added. I've pleaded several times, but with zero success so far (see links above).

If you all have better suggestions, let's hear them. But even if none of them are ideal, isn't something better than nothing?

I like Bacon's and Emma Moon's "sich herumdrücken" from the links. It doesn't fit every context but it's a good start.

#3, "If you all have better suggestions, let's hear them. But even if none of them are ideal, isn't something better than nothing?"

In other words: if I don't come up with a better suggestion, I am not allowed to criticise a poorly documented suggestion that appears to be wrong???
The way I see it, "something" is only "better than nothing" if it's adequately documented. This suggestion isn't.

I fully agree with oreg's comments in this thread.

re #4: Did you look at the other previous discussions? Taken together, they include several suggestions, and surely any of them, or two or three together, would be better than nothing. At the very least you could take the trouble to compare them and say something about which ones are better than others, and why.
