Usage

What does enter- mean? Enter- is a combining form used like a prefix meaning “intestine.” The intestines are the long tract of the digestive system that runs from the stomach to the anus. Enter- is often used in medical terms, especially in anatomy and pathology. Enter- comes from the Greek énteron, meaning “intestine.” A scientific term for the digestive tract (alimentary canal) is enteron, which comes from this same Greek root. The word dysentery, literally meaning “bad bowels,” also derives from the Greek énteron. Enter- is a variant of entero-, which loses its -o- when combined with words or word elements beginning with vowels. Want to know more? Read our Words That Use entero- article.

Etymology

Origin of enter

First recorded in 1200–50; Middle English entren, from Old French entrer, from Latin intrāre “to enter,” from intrā intra- ( def. )

Explanation

To enter is to go inside or into a place. When you enter your house after school, you might pet your cat and take off your shoes. You might enter the kitchen to see what's for dinner, or enter the library to look for a book to read. In both cases, you go from one place into another, through a doorway. If you're an actor, the word enter takes on a different meaning: to appear on the stage during a play. The stage directions might read, "Enter the King, stage left." Countries also enter wars, and people enter contests — they register or become involved.
