economic

Origin:

late Middle English: via Old French and Latin from Greek oikonomikos, from oikonomia (see economy). Originally a noun, the word denoted household management or a person skilled in this, hence the early sense of the adjective (late 16th century) 'relating to household management' Modern senses date from the mid 19th century

Economic means ‘concerning economics’: he’s rebuilding a solid economic base for the country’s future. Economical is commonly used to mean ‘thrifty, avoiding waste’: small cars should be inexpensive to buy and economical to run.
