My book "visual guide to grammar and punctuation" says on pg 61.
subordinating conjunction. They link a subordinate (less important) clause to a main clause".."e.g. Tigers only hunt when they are hungry".
What happens if I change it to the still understood "Tigers only hunt when hungry" — now that "when" is linking to just a word (I guess the question also could be for just a phrase), is it still considered a subordinating conjunction?
thanks
