I have just read DEPENDANT in a New Scientist article. As I have always spelled it DEPENDENT, I looked it up in Chambers, which gives two alternative meanings - the first however gives dependAnt with dependEnt as an alternative; the second the other way round. (I won't prejudice your hoped-for responses by giving the meanings, though I will say they weren't very distinct from each other.)
Is there are distinction between DEPENDENT and DEPENDANT? If so, what is it?
