The words built on the same word-part

Each word below begins with the same letters this one begins with. A shared word-part shows a family. It does not settle what any one of them means, so each word carries its own uses on its own page. Scholars call that shared part the stem.

How the numbers are counted

Every count on this page comes from STEP Bible's tagged Hebrew and Greek text, the same text the ledger prints. A use is counted once each time the tagging marks a word with this key.

Spellings are counted as the Greek text spells them, with the sentence's own punctuation taken off the word first, so a form that ends a clause is not counted as a second spelling.

The family is read from the lexicon by the stem the two words share, with the accents off, and a person or a place named on the stem is left out.
