Well, I'm curious to know how to say a hot question in other ways. By means of hot I want to say important evolving question...
Secondly, I used word "useful" "fruitful", I want synonyms for it. Kindly don't mention google search I already did that and found these words (below) But I want a unique word like futile for useless. Thanks in advance
beneficial, advantageous, helpful, worthwhile, profitable, gainful, rewarding, productive, constructive, effective, efficacious, valuable, fruitful
