Completing British citizenship - what is a "dependent"

Hi all,

Full disclosure, I am asking this on behalf of a friend:

"I currently hold an ILR and am applying for citizenship, I am married and my spouse holds a leave to enter visa, he is not applying for citizenship at this time.

In my citizenship application it asks if I have any dependants who are not applying at this time - does my husband fall into this category?

We are both Indian nationals, have no children and both employed full time."

I've tried searching for a clear definition of ***what*** exactly a dependant is but can't find exactly what it is we're looking for.

Many thanks in advance!
