We have several dictionaries. In the homeschool community many like one from the 1800s that is in the public domain.
One of our favorites is Webster’s New 20th Century Dictionary of the English Language. It is unabridged, and was published in 1952. It has many special features such as Latin and Greek Bible name pronunciations.
I recently purchased a dictionary published in the 1990s on Amazon, because I didn’t want a new, politically correct version.
You can choose your favorite time period and get from then:)
Bob Jones University publishes a Christian Student Dictionary that is nice.
