I am looking for recommendations on dictionaries suitable for English language learners (immigrants) in middle school. English-Spanish and Spanish-English dictionaries will be needed.
When my wife came to Spain she got herself a Webster's New World Pocket Spanish Dictionary.
It was affordable, small enough to be carried in a bag and complete. She is a teacher (worked as a teacher in USA and as an English teacher in Spain), so she new what she was looking for when she got hers.
