| Aug 16, 2018 at 12:42 | comment | added | Gerald Edgar | Yes, "power" is sen in old writings in English. The power of the real line is $2^{\aleph_0}$. | |
| Aug 16, 2018 at 12:25 | comment | added | Robert Furber | There is also "puissance" in French, which can often be seen in old articles by Kuratowski or Sierpinski. | |
| Aug 16, 2018 at 12:21 | comment | added | Robert Furber | The natural cognate of "Mächtigkeit" in English is "mightiness", though it seems to have never been used as a translation, "power" being used instead, as pointed out by David Roberts. An example of an old book where it is used is: books.google.dk/… The phrase "power of the continuum" also seems to have lasted a bit longer than "power" as a general term for cardinality. | |
