What's the difference between "man" and "en" in this sence?

[Deliciae]

Nothing at all. You could write this sentence with 'man' instead. :)

While these two pronouns are synonymous in meaning, keep in mind that 'man' can only be used as a subject, while 'en' works as an object pronoun as well, and has a corresponding possessive pronoun: 'ens'.

[Albantar]

Tusen takk!

[maehovland]

so you can't use 'mans' to mean ones?

[Deliciae]

Correct.

Could I also use "edit"?

[Friesk]

Edit is redigere, change is endre.
