'Economic' and 'economical': Which is which, and how can we remember the
difference?
These words are closely related, but they do not have the same meaning.
However, many people, including native speakers, do not seem to know this,
and use "economical" when they should be using "economic".
This is probably because "economical" sounds like an adjective,
while "economic" sounds as if it is the singular form of the
noun "economics" (the academic subject that you are studying
at Keio). (In fact, of course, "economics" is uncountable and "economic" does not exist as singular noun.)
Why are there two adjectives that look so similar but have different meanings?
This is because the noun "economy" has more than one meaning.
Look "economy" up in an English-English dictionary, such as this one or this one. (Note that in the case of the Longman online dictionary you will actually
have to type "economy". However, it is useful because it has
many examples.) They divide the meaning of the word up in different ways,
but there are two basic meanings, one to do with the way in which money works
(we will call this "meaning 1"), and one to do with saving money
and not wasting things (we will call this "meaning 2").
(While you are looking at the dictionary entries, note the meanings and
uses of the word "economy" itself. Note also that when you are
referring to the economy of a particular country, you should say either
"the economy of Japan", "the Japanese economy"OR (without
""the") "Japan's economy".
It would be a good idea to learn some sentences to help you to remember this.)
The academic subject "economics" and the adjective "economic"
are both related to meaning 1. Look them up in an English-English dictionary. Again note the use as well
as the meaning of the words. Note that when "economic" comes
after a noun, it can only mean "profitable".
One way of remembering that "economic" is to do with the way
in which money works would be to learn it in a sentence like this one:
Economics involves the study of economic issues.
One way of remembering that "economic" after a noun means "profitable"
would be to learn it in a sentence like this one:
Do not invest in a business unless it is economic.
On the other hand, "economical" is related to meaning 2. Look it up in an English-English dictionary.
One way of remembering that "economical" is to do with saving
money would be to learn it in a sentences like this one:
In order to save the environment we must be economical in our use of resources.
An economical car needs an efficient engine so that it does not waste gasoline.
