Do I need to learn Hebrew or Greek to do a word study?

No. You need to be able to see which original word is behind the English, what range of meaning it carries, and where else it appears. That's what a word study tool gives you. Learning the languages properly is a different and much longer project.

What's the best app for Hebrew and Greek word studies?

Blue Letter Bible if you want the deepest free set of tools and don't mind a dated interface. Logos if you're doing academic work and have a budget. BibleKey if you want to tap a word mid-sentence and keep reading.

What are Strong's numbers?

An index that assigns a number to every Hebrew and Greek word in the Bible, so an English reader can look up the original without knowing the alphabet. Almost every study tool is built on them.

Can a word study go wrong?

Easily. The classic error is deciding a word always means what its root once meant — that 'dynamite' tells you what Paul meant by dunamis. Words mean what they mean in context. A good tool shows you the usage, not just the etymology.

What's a good first word to study?

Try 'love' in John 21:15–17, where the Greek changes between agapao and phileo three times in a conversation English flattens completely. Or hesed in the Psalms, which has no single English equivalent.

What translation loses

Translation is a series of compromises, made carefully, and mostly invisible. Some of them matter.

English has one word for love. Greek has several, and John 21 uses two of them in a single conversation — Jesus asking with one, Peter answering with another, three times. In English it reads like repetition. In Greek it's the whole point of the scene.

Hebrew hesed gets translated as lovingkindness, steadfast love, mercy, loyalty and faithfulness, depending on the verse and the committee, because there is no English word for a covenant loyalty that keeps showing up when it doesn't have to.

You don't need Greek to see this. You need to be shown where the seams are.

What a word study actually tells you

The original word — in Hebrew or Greek, with a transliteration you can pronounce.
Its range — not one definition, but the field of meaning it covers.
Where else it appears — usage is what settles meaning, far more than etymology does.
What the translators chose — and, sometimes, what they had to give up.

The mistake to avoid

The most common error in word studies is the root fallacy: assuming a word must mean what its parts once meant. Dunamis is the root behind "dynamite", so people say the gospel is dynamite. Paul had never heard of dynamite. The word meant power, capability, strength — and what it means in Romans 1:16 is settled by Romans, not by Alfred Nobel.

Usage over etymology, every time. Good tools show you the verses; that's the actual evidence.

Three words worth starting with

hesed — Psalm 136

Twenty-six verses, and the same phrase closes every one of them. Whatever hesed is, the psalm's argument is that it doesn't stop.

agape / phileo — John 21:15–17

Read it in English, then look at which Greek word is used where. The conversation changes shape.

shalom — Isaiah 9:6

Usually rendered "peace", but it's much larger than the absence of conflict: wholeness, completeness, everything in its right place.

Every word has a history.
