The five Ws
The Five W’s, Five Ws and How, 5W1H, or Six Ws are questions whose answers are considered basic in information gathering or problem solving.
Quis, quid, quando, ubi, cur, quem ad modum, quibus adminiculis.
(Who, what, when, where, why, in what way, by what means)
The tale of “The Elephant’s Child”
I keep six honest serving-men
(They taught me all I knew);
Their names are What and Why and When
And How and Where and Who.
