As you probably know, English is the richest of all the languages known to mankind, past or present. It keeps churning out new words by borrowing everything, everywhere, from everyone; and that's not all.
Once a foreign word is swallowed, digested, and accepted into everyday speech, it becomes English. The major problem is that few of us can keep up with such an explosion of words, much less the thousands that have come to us from the past.
That's why great efforts have been made to provide the multitudes of words that you can view in this Word Info Index where you can examine the thousands of words which have been inherited from the past and the vocabulary which is continuously being created from those historical word-family units.
