The silent W: write, wrong, two, sword, answer
Silent Ws come in two kinds, and both were once real sounds.
The first is the wr- at the start of a word. Old English wrītan and wrang began with a rounded W gliding into R. Around the 1600s, speakers dropped the W and kept the R — the same century that silenced the K in knight and know. Every wr- word went together: write, wrong, wrist, wreck, wrap, wrinkle.
The second kind is a W swallowed by its neighbors: next to a rounded "oh" or "oo" vowel (two, sword), or in a weak syllable of a long compound (answer). Here the change was gradual and word-by-word, which is why the W survives in related words like twelve, twenty and swear.

write
Write comes from Old English wrītan, once said with a real W. Writing first meant scratching runes into wood. Here is how the W went silent.
- Then · Old English
- wrītan
- Say it
- RITE

wrong
Wrong once meant "crooked, twisted" and was said with a real W. It is related to wring. Here is how the W went silent while the spelling stayed.
- Then · late Old English
- wrang
- Say it
- RAWNG

two
Two comes from Old English twā, said with a real W. The W is still heard in twelve, twenty, twin and between — the same root, a sound that survived.
- Then · Old English
- twā
- Say it
- TOO

sword
Sword comes from Old English sweord, and the W was pronounced. German Schwert still has it. Here is how English lost the W but kept the spelling.
- Then · Old English
- sweord
- Say it
- SORD

answer
Answer comes from Old English andswaru, "a sworn reply" — it contains the word swear. That is where its silent W comes from.
- Then · Old English
- andswaru
- Say it
- AN-ser
The American R is a little bit W
The American R is made with the lips slightly rounded, which is a faint echo of the lost W in write and wrong. Don't add a W — but don't spread the lips flat either.
Where the W survived
The proof that these Ws were real is in their relatives: two lost it, but twelve, twenty, twin and between kept it. Answer lost it, but swear — the word hidden inside answer — kept it.
Questions people ask
+Why is the W silent in write and wrong?
English speakers simplified the wr- cluster to r- around the 1600s, after the spelling had already been fixed.
+Why is there a W in two?
Old English twā was pronounced with a W. It was later absorbed into the rounded vowel. Twelve and twenty, from the same root, kept it.
