Word Lists

Word lists are older than dictionaries. The first monolingual English word list was Robert Cawdrey's A Table Alphabeticall, published in 1604. It listed "hard words" borrowed from other languages with brief glosses. No definitions in the modern sense. Just the word, a short explanation, alphabetical order. Cawdrey was a schoolteacher. His word list was a teaching tool, not a reference work.

Samuel Johnson's Dictionary of the English Language appeared in 1755 and changed what a word list could be. Johnson grounded his entries in quotations from English literature, showing each word in context. He numbered subtle shades of meaning. He spent nine years on it with six assistants, working in a house off the Strand in London. It was not the first English dictionary. But it was the first one treated as the standard of the language.

Across the Atlantic, Noah Webster published A Compendious Dictionary of the English Language in 1806 and An American Dictionary of the English Language in 1828. Webster wanted American English to have its own identity. He simplified spellings: "colour" became "color," "centre" became "center." His word lists were prescriptive. He believed dictionaries should guide usage, not just record it.

The most ambitious word list project ever attempted in English began in 1857 when the Philological Society proposed a new dictionary on historical principles. James Murray, a self-taught Scottish scholar, became editor in 1879. He built a corrugated-iron shed in his garden and called it the Scriptorium. Volunteer readers across the English-speaking world sent in quotation slips showing words in use. Murray sorted them, edited them, and published the dictionary in fascicles. The first one covered A through "ant" and appeared in 1884. Murray died in 1915, having completed about half the alphabet. The finished Oxford English Dictionary appeared in 1928: ten volumes, over 250,000 entries, nearly two million quotations.

The word lists on this page follow that same tradition of systematic vocabulary collection. Every word is validated against a standard English dictionary compatible with the NASPA Word List (NWL2023, effective February 29, 2024) used in competitive Scrabble in the US and Canada, and Collins Scrabble Words (CSW24, effective January 1, 2025) used internationally. CSW24 contains over 290,000 words. Whether you are studying for a Scrabble tournament or just curious about what 5-letter words start with Q, the data is the same data that competitive players use.

Step 1. Select a word length from the filter above, or choose a starting letter.

Step 2. Combine filters to narrow results. For example, 5-letter words starting with S.

Step 3. Browse the results list. Every word is a valid English word accepted in competitive word games.

Step 4. Click any word to see its definition.

Word length is the single most useful filter for word game players. In crosswords, the grid fixes the answer length exactly. In Scrabble, the board position often constrains how many tiles you can place. In daily word guessing games like Lexle, the answer is always a specific length.

Browsing by length also reveals patterns you would not notice otherwise. There are far more 5-letter words starting with S than starting with X. The letter J appears in relatively few 4-letter words. These distributions matter when you are deciding which letters to keep on your Scrabble rack or which starting letter to guess first in a word guessing game.

Research on vocabulary acquisition consistently shows that repeated exposure to words improves retention. A 2022 meta-analysis by Kim and Webb analyzed 48 experiments from 37 studies and found large effects of spaced practice on second language vocabulary learning and retention. Spaced practice means encountering words at intervals rather than all at once.

Word lists provide structured exposure to words you might not encounter in everyday reading. Browsing all 7-letter words starting with P surfaces words like PLUMB, PLUME, and PLUNK that you might not think of spontaneously. This is particularly effective when combined with active recall techniques like flashcards or fill-in-the-blanks exercises, both of which were shown to benefit from spaced practice in the same meta-analysis.

A 2024 study published in Frontiers in Psychology investigated the effects of an official word list on university learners' vocabulary knowledge. It found that listed words had significantly higher recognition rates than off-list words, confirming that structured word lists have a measurable impact on what learners actually know.
