I find the words 'effective' and 'affective' confusing. When should each of these be used?
Post Script: I have checked the dictionaries that I use (of course, not the ones that run in several volumes). None of them defines the word "affective", but each of them defines the word "effective". Believe me, the word "affective" is not a general reference. Can you please define the word "affective" and cite a few example sentences?
