Amy Lightfoot answers:Economic and economical

Economic is used to describe anything which has a relationship with the economy (money and trade) of a place or the finances that someone or a group of people have. Common uses include:

economic growth
economic development
economic reform

Economic can also refer (and this is where it might get confusing) to the profitability or successful of a business. For example:

Unless we start making money, it will not be economic to keep this supermarket branch open.

Similarly (but slightly differently!), economical means using money or resources in a way which minimises any waste of money or any other resource. Have a look at these examples:

It’s important to be economical with our oil reserves – they may soon run out.

It can be very economical to rent out an empty room in your house – that way you will be able to share some of your costs.

Try to be economical with the fabric when you cut out the shapes – we haven’t got any more.

So while economic describes anything economy-related or the success of a business, economical refers to avoiding waste.

Economical is probably more commonly used in its opposite form: uneconomical. For example:

Driving to work alone is uneconomical if you have a colleague who lives nearby.

An interesting idiom is being economical with the truth, which means only saying what needs to be said and not revealing all the details, even though they might be important. It’s not quite as bad as lying!
