Random Word Generator - Generate Words by Part of Speech

How to use this tool

1. Select how many words to generate and which part(s) of speech.
2. Click Generate to get your random words.
3. Copy the list or click Regenerate for a new set.

Uses for random words

• Creative writing: break writer's block by building a story around unexpected words
• Brainstorming: random words trigger associations that lead to novel ideas (lateral thinking technique by Edward de Bono)
• Passphrases: 4 random words form a memorable, high-entropy passphrase (Diceware method)
• Improv games: random word prompts for acting exercises and storytelling

Diceware passphrase security

A 4-word Diceware passphrase (from a 7,776 word list) has 7,776⁴ = ~3.6 trillion combinations. A 6-word passphrase has 2.2 × 10²³ combinations - extraordinarily secure yet memorable: "correct horse battery staple".

Word list size and entropy

Passphrase security is measured in bits of entropy: each additional word multiplies the search space. For a list of W words and n words in the passphrase:

Entropy = log₂(Wⁿ)

• 7,776-word Diceware list, 4 words: log₂(7776⁴) ≈ 51 bits
• 7,776-word Diceware list, 6 words: log₂(7776⁶) ≈ 77 bits (excellent)

NIST recommends at least 64 bits of entropy for online accounts; 80+ bits for offline attack resistance.

Parts of speech filter

Filtering by part of speech is useful for generating grammatically structured prompts. For example, a random “adjective + noun” pair like fractured whisper or luminous anchor makes an evocative product name or story title. Combining a random “verb + noun” pair gives a potential action sequence for game design or fiction.

Lateral thinking with random words

Edward de Bono’s Random Entry technique uses a random word to force new associations when problem-solving has stalled. The process:

1. Generate a random word (e.g., bridge).
2. List the properties of that word (connects two sides, often over water, built under tension).
3. Force-connect those properties to your problem (what if we “bridged” the two user groups instead of choosing one?).

The non-obvious connection breaks cognitive fixedness and often surfaces genuinely new ideas.
