It should be noted that house-elves did not verbally cast spells, rather their magic was performed through their sheer force of will and intent.

House-elves had access to their very own brand of wandless magic that only they could use. Harry Potter once remarked that house-elves were actually much more capable of wielding advanced magic than wizards, despite not having wands. Bartemius Crouch Snr suggested that Amos Diggory was implying that "I routinely teach my servants to conjure the Dark Mark", suggesting that it would have been possible for Winky to use the spell if she had the knowledge. It is implied that with a wand and the proper knowledge, house-elves might be able to do other magic, as Winky was accused of using the Morsmordre spell to conjure the Dark Mark in the sky, though it was in fact cast by Bartemius Crouch Jnr. In 1998, Dobby disarmed Narcissa Malfoy by snapping his fingers. Winky's magic broke when she was rendered unconscious. In 1993, Dobby protected Harry Potter by using his magic to throw Lucius Malfoy across the floor, and in 1994, Winky used her magic to bind Barty Crouch Jnr to her, to make sure he did not escape. Bound by the laws of his kind, Kreacher was able to Disapparate out of the cave and return to Regulus because Regulus had told Kreacher to return after the task was finished. After using Kreacher for his purposes, Voldemort left him there to die. To test the security around the locket Horcrux in the 1970s, Lord Voldemort required a house-elf for the job, and Regulus Black nominated Kreacher.
