Monday, 17 October 2941 T. A.: What was the word for "Friend" in Dale?

Were the Dwarves of Erebor as trusting as those of Moria?

About this time, in 2941 T. A., Fili, Kili and Bilbo finally managed to locate the Secret Door. It was midday when they began their ascent, and it may have taken them about two hours or more until they reached the cliff that would become known to them as the Doorstep. The afternoon was wasted with vain attempts to open the door, even including uttering "fragments of broken spells". (Say "Friend" and enter would not work here?)  They left for their base-camp in the evening, returning there probably in the early dark and bringing a lot of excitement there.
