Other forms: word-hoards
A word-hoard usually refers to a collection of all the great vocabulary a person knows.
Word-hoard comes from an Old English term meaning "treasury of words." It appeared in its modern form in the mid-1800s as a poetic term. Today, it often refers to a person's vocabulary, but it can also refer to all the words in a single language or the sum of words in a particular dictionary. A paperback print dictionary may have a word-hoard of 170,000 words. English's word-hoard is sometimes said to be around a million. Now that's a treasure trove or hoard of words!
