I found out that Logos incorporates the root words for Greek lemmas in English Bibles using the reverse interlinear. How may these root terms be applied in genuine Bible study? I would like to begin with a few definitions of my own. A manuscript is a form of a term that relates to the word used by the Biblical author. The lemma or lexical form of a word relates to how it is "looked up" or referred in a classical dictionary or lexicon. The word that gives rise to the lemma is known as the root. The root word is a basic word from which other words are developed. Root words are usually verbs and functional adverbs. Simply put, manuscript forms are generated from lemmas, which in turn are derived from roots.
