About this app

TriLex is a fast, offline Hebrew lexicon and Greek lexicon for anyone reading the Hebrew Bible or Greek New Testament in the original languages. Use it like a Bible dictionary: look up a word two ways — by its dictionary (lexical) form, or by typing the exact inflected form as it appears on the page — and TriLex finds the entry either way.
 
FEATURES
 
• Three languages, one Bible lexicon — a Hebrew lexicon for Biblical Hebrew and Aramaic and a Greek lexicon for the New Testament, switching languages with a tap, with built-in Hebrew-script and Greek keyboards. Letters that can't continue your search are dimmed.
 
• Lexical or inflected lookup — Don't know the lemma? Type the word exactly as it's printed in your text. TriLex identifies the underlying dictionary form and shows how it's parsed grammatically.
 
• Instant results — No loading screens. The result list narrows with every letter you type, entirely offline.
 
• One card per word — See the gloss, frequency, part of speech, and an example verse at a glance.
 
• Full lexicon entries — Beyond the quick definition, read the complete Brown-Driver-Briggs (BDB) Hebrew lexicon entry for Hebrew and Aramaic, or the complete Liddell-Scott-Jones (LSJ) Greek lexicon entry for Greek, with pinch-to-zoom.
 
• Browse by letter — Explore the full lexicon of any of the three languages letter by letter, like the page headers of a printed Bible dictionary.
 
• Built for readers — Whether you're a seminary student, a pastor preparing a sermon, or working through your first year of Biblical Hebrew or Greek, TriLex is a Bible lexicon built to answer "what does this word mean?" as fast as possible.
 
TriLex draws on scholarly sources, so the words on your screen carry the weight of real lexicographic scholarship:
• Brown-Driver-Briggs for Hebrew and Aramaic full entries
• Liddell-Scott-Jones (1940) for Greek full entries
• MACULA Hebrew (Westminster Leningrad Codex) and MACULA Greek (SBL Greek New Testament) for inflected forms
• Open Scriptures Hebrew Bible Project for Strong's and BDB cross-references
• World English Bible for example verses
 
No account. No ads. No internet connection required once installed: your Bible lexicon and Bible dictionary for the original languages, wherever you are.
