What is the relationship between Collins Scrabble Words and SOWPODS?

Collins Scrabble Words (CSW) IS SOWPODS — it's the official published name of the same word list. SOWPODS was the informal name given to the merged international dictionary in the late 1980s. When HarperCollins became the official publisher, they branded it 'Collins Scrabble Words' (CSW). The word list is identical; only the name differs. Players still use 'SOWPODS' informally, while tournaments and official documents reference 'CSW'.

What is the latest edition of Collins Scrabble Words?

The latest edition is Collins Scrabble Words 2024 (CSW24), which added several thousand new words to the previous CSW19 edition. New editions are typically published every 4-5 years, coinciding with updates to Collins English Dictionary. Each edition adds words that have entered common usage and occasionally removes words deemed no longer in use.

How many words are in Collins Scrabble Words?

Collins Scrabble Words contains approximately 280,000 valid entries. This makes it the most comprehensive English-language Scrabble word list available. It includes every word from the North American TWL dictionary (approximately 190,000 words) plus an additional 90,000+ words from British, Australian, South African, Indian, and other world English sources.

Collins Official Scrabble Dictionary (CSW): The Published SOWPODS

June 14, 2026 7 min read Word Finder

Collins Scrabble Words (CSW) is the official published edition of the international Scrabble word list most players know as SOWPODS. Published by HarperCollins, it's the most comprehensive English-language Scrabble reference with 280,000+ entries — and it's the definitive authority for tournament play outside North America.

Collins and SOWPODS: The Same List

The first question most players ask: what's the difference between Collins Scrabble Words and SOWPODS? The answer is simple — they're the same word list under different names.

💡 The Name Relationship

SOWPODS is the informal player name. Collins Scrabble Words (CSW) is the official published name. The word list is identical — CSW is simply what you buy in a bookshop or reference in tournament rules. Think of it like "tissues" vs "Kleenex" — same thing, different label.

When WESPA (World English-Language Scrabble Players Association) specifies the official dictionary for international tournaments, they reference "Collins Scrabble Words" — not "SOWPODS." But players universally use both names interchangeably, and no one will correct you in a Scrabble club for saying either.

History of Collins Scrabble Words

The publishing partnership between HarperCollins and the Scrabble community has a rich history spanning several decades.

🧩 CSW Publishing History

1980s: Chambers Dictionary provided the British word list (OSW). Collins was not yet involved.

1991: First SOWPODS list compiled (merging OSW + TWL). HarperCollins begins publishing it.

2007: Collins officially brands the list "Collins Scrabble Words" (CSW07). Regular update cycle begins.

2019–2024: CSW19 and CSW24 editions add thousands of new words from modern English usage.

HarperCollins leverages their massive lexicographic database (the Collins Corpus, with over 20 billion words of text) to identify new entries. Words must show sustained usage in published sources before being added to CSW.
