Word root breaker

Type a word to see its possible prefix, Latin or Greek root and suffix, what each part means and which other words share it.

biography

biography : bio + -graphy

[Greek bio ‘life’ + Greek -graphy ‘writing, recording or describing; a field of study’]

Checked. Each Latin or Greek part lists biography, or a word inside it made of the same parts, in our examples checked against Wiktionary.

  1. root bio Greek

    life

    [Greek βίος (bíos) ‘life’]

    Also in biology antibiotic biodegradable symbiosis

    Wiktionary: bio
  2. suffix -graphy Greek

    Wiktionary: -graphy

Other ways to split it

  • bio ‘life’ + graph ‘write, draw, record’ + -y ‘state, quality or act (forms nouns)’

Possible parts, not a verdict. Many English words were borrowed whole, often through French, so these parts show the Latin or Greek building blocks rather than how the word was put together in English.

How the root breaker reads a word

It compares your word with a hand-checked list of 467 prefixes, Latin and Greek roots and suffixes, looking for ways to cover every letter: prefixes, then roots or a whole English word, then suffixes. A connecting -o- (bi·o·logy), a silent final e and the usual spelling changes (believe loses its e in unbelievable) are allowed.

Each split is scored: long matches beat tiny pieces and parts from one language beat mixtures. Close runners-up are listed, because the same letters can come from different roots: ped is ‘foot’ in pedal but ‘child’ in pediatrician.

A split is marked checked only when each Latin or Greek part lists your word (or a word inside it made of the same parts) in our examples checked against Wiktionary. Anything else is a pattern match, not checked; on short words or short roots, where chance matches abound, we hold it back. Words that only look divisible, like decade (not de- + cad ‘fall’), get what the dictionaries say.

Questions

Is the split the real origin of the word?

Not necessarily. The tool finds parts that fit and ranks them, but English often borrowed a finished word from French or Latin instead of building it from parts. Read the result as the word’s Latin or Greek building blocks, and check the linked dictionary entry for its actual history.

Why does it show more than one split?

The same letters can belong to different roots. In incredible, in- could mean ‘not’ or ‘into’; the tool favours ‘not’ because the word ends in an adjective suffix, and lists the other reading so you can decide.

Why does it refuse to split some words?

If nothing in the list fits well, it says so instead of guessing. Native English words such as happiness, English compounds such as pineapple, names and borrowings from other languages usually have no Latin or Greek parts in the list.

Where do the meanings come from?

Every prefix, root and suffix was written for Etymoasis and checked against its Wiktionary entry, which is linked from each part. The data is shared under CC BY-SA 4.0, like Wiktionary itself.

Does anything I type leave my browser?

No. The word list and the splitting run in your browser; the site never receives the words you type.
