n- be it a reference to rank or dimension works fine. Can't see an alternative but to get used to a few synonyms. Is the variation a hard thing for a newcommer to get used to? Maybe it isn't. Give the authority and insight that is in the j language, it seems a little odd at first to accept that there might not be an answer.
Perhaps it's the presentation that's important. Like by contrast to any C-style language, arrays are extremely flexible and fluid in J. You'll find yourself wanting to use arrays, rather than avoid them if at all possible. "Maybe it just varies according to your audience." Agree.
