Hard-to-Find Words Dictionary
by Heron Books
This is a dictionary of hard-to-find words and phrases structured originally around the Heron Forms 3-6 Reading Program, but has wide use for students building vocabulary (words and phrases) in independent reading.
Here "hard-to-find" means words and phrases found in books starting at an elementary reading level, but which are generally difficult to find in dictionaries at a student level (such as the Webster's New World Student's Dictionary).
It includes a section of translations of foreign phrases used in books commonly read by children. This dictionary is useful for reading programs and home schooling.
