Editorially reviewed: September 2026.
This page is a focused reference for the letter W, the twenty-third letter of the English alphabet. It covers ordinary English usage first, then places the character in its broader historical and digital context.
Overview
- Alphabet position: 23 of 26.
- Letter type: consonant.
- Uppercase and lowercase: W and w.
- Example words: water, away, write, who.
- Unicode (Basic Latin): W is U+0057; w is U+0077.
English sound patterns
W usually represents the sound heard at the start of water. It is silent in some wr- words such as write, and spellings such as who show that historical spelling patterns can be irregular.
W often combines with vowels and with H. Its English name, double u, reflects the history of its written form rather than a rule about how it is pronounced in words.
English spelling should not be read as if every character had one fixed sound. The International Phonetic Association provides a separate phonetic alphabet precisely because speech sounds and conventional spelling are different systems.
Why W is worth noticing
W is distinctive both in name and spelling behavior. Its English name, double u, reflects historical letter development, while its normal consonant sound is heard in water. Silent W in write and irregular wh words show that its modern pronunciation cannot be predicted from letter shape alone.
Other uses of W
W is the SI symbol for watt. Lowercase w is also used as a variable in many fields, where its meaning depends on context.
The alphabetic character itself does not guarantee a particular symbolic meaning. Readers should use the surrounding discipline, notation, and capitalization to determine what it represents.
Where W fits in alphabet history
The letter’s deeper background belongs to the history of the Latin alphabet rather than to a modern symbolic story. The Metropolitan Museum of Art documents the broader path from early West Semitic alphabetic writing through Phoenician and Mediterranean adaptations toward Roman letters.
A letter’s modern appearance is shaped by centuries of writing and typography. Serif, sans-serif, script, and display forms can look different while still representing the same character.
Digital representation
Computers store this letter as a Unicode character rather than as a picture of a particular font. Uppercase and lowercase have their own code points in the Basic Latin block. For W, the uppercase code point is U+0057 and the lowercase w is U+0077.
Software can compare uppercase and lowercase as different characters even when people recognize them as forms of one letter. This matters in case-sensitive searches, code, and account credentials.
Clear reading and writing tips
- Practice W in several real words rather than attaching one broad “symbolic meaning” to the character.
- Use sound patterns as learning aids, not as rules without exceptions.
- Check a reliable dictionary when spelling and pronunciation do not line up as expected.
- Learn uppercase W together with lowercase w, including how both appear in different readable fonts.
- In educational graphics, do not rely on color or letter shape alone when essential meaning must remain accessible.
