I am trying to find alternative ways to refer to a very necessary thing or thing that someone must have. Can I use the word needful for this purpose? A person said that needful means the thing needs something but not that somebody needs it.
I will only offer this data point: In 1991, best-selling author Stephen King published a novel (later made into a movie), called Needful Things. From the Wikipedia entry:
A new shop named "Needful Things" opens in the town of Castle Rock, Maine, sparking the curiosity of its citizens. The proprietor, Leland Gaunt, is a charming elderly gentleman who always seems to have an item in stock that is perfectly suited to any customer who comes through his door. ... It is revealed that Gaunt has traveled the world for centuries, selling useless junk that appears to be whatever the customers desire most.
It is obvious that the meaning of needful in this title is not "things that are needy" but "things that people think they really need" (i.e., that they find necessary and feel they simply have to possess).
Now, I will agree in advance that this usage is a bit formal and obscure, with an air of the rural or rustic about it, and that it is not in common usage. Nevertheless, the fact that a best-selling author can use the word in the title of a popular novel suggests that the word is not so obscure that people will not understand it.
There are plenty of little-used words that native speakers understand without using themselves. This brings up the question of what constitutes usage. If everyone understands a word, that seems to me to be evidence that the word is common even if it is rarely spoken. How often do we use words like "umbrage"? Rarely, if ever. Yet when they come up we know exactly what they mean. That feels to me like some form of currency.
Merriam-Webster lists two meanings for the adjective needful: being in need and necessary, requisite. It also lists two meanings for the noun needful: something needed or requisite and money.
I just thought of clearing some air on 'please do the needful'......most of the people mentioned that the said phrase is used only by Indian English speakers but the fact is it comes from both British and American English well into the early 20th century.
The Oxford English Dictionary lists examples of usage from 1709 (Richard Steele in the Tatler), 1771 (Samuel Foote in Maid of Bath), 1821 (Maria Edgeworth in a letter), 1831 (Walter Scott in his journal), 1929 (I. Colvin in his Life of Dyer).
