Most of the Old Testament was written in Hebrew, with portions in Aramaic; the New Testament was written in Koine Greek. A translation conveys these texts in another language. A lexicon explains a word's uses; morphology describes its grammatical form; syntax describes how words relate within a sentence. Semantic range means the possible senses of a word across different contexts.

Languages do not map word for word. Translation differences can reflect grammar, an ambiguous phrase, translation goals, or a different underlying textual reading. Language tools help you investigate the reason. They support careful reading; knowing a Greek or Hebrew word alone does not settle an interpretation.

1. Compare two translations and identify a specific difference. 2. Use a language tool to find the lemma (dictionary form) and its grammatical form in that verse. A Strong's number is a lookup aid, not a definition or argument. 3. Read the lexicon's relevant senses and examples. Choose the sense supported by this sentence and the author's usage; do not insert every possible meaning. 4. Check syntax and a reliable commentary. Record what is clear, what is uncertain, and whether the language evidence actually changes your reading.

In John 3:8, the Greek word pneuma can refer to wind or spirit. The saying connects the wind's movement with birth from the Spirit. Read verses 5–8 and compare translations before deciding how each occurrence functions. The example shows why context matters more than replacing every occurrence with one dictionary gloss.

Assuming a word's root determines its meaning; importing all dictionary senses into one verse; treating an interlinear as a complete translation; assuming Greek or Hebrew has a hidden meaning unavailable in translation; building doctrine on a grammatical claim you have not checked.
