Silent Letters, Strange Vowels: Why English Spelling Makes No Sense

Introduction

Why is English spelling so confusing and unpredictable? You write “knight” but say “nite.” “Colonel” becomes “kernel.” And what about “though,” “through,” and “thought”? English looks like a spelling puzzle — and for many learners, it feels that way too.

But there’s a reason for the chaos. English is a mix of languages, with layers of history, sound shifts, and spelling traditions that don’t always line up. This post breaks it down and shows how it all happened.

Why English Spelling Is So Confusing

1. Silent Letters Are Everywhere

• Know, write, gnome, psychic — those first letters used to be pronounced.

• Over time, the Great Vowel Shift and other sound changes silenced many consonants.

• But the spelling stuck — because writing systems are slow to change.

2. Words Come From Many Sources

English borrows from Latin, Greek, French, Germanic, and even Norse and Arabic.

• “Debt” comes from Latin debitum.

• “Psychology” keeps its Greek root.

• “Colonel” is from French coronel, via Italian colonnello.

These borrowings often keep original spellings — even if the sounds don’t match.

3. The Great Vowel Shift

Between 1400–1700, English vowels shifted dramatically:

• “bite” used to sound like beet,

• “meet” like mate,

• “name” like nah-meh.

But we kept spelling words the old way. This created a major gap between spelling and pronunciation.

4. No Spelling Reform Took Hold

Unlike Turkish or Korean, English never underwent major spelling reform. Attempts were made — even Noah Webster tried to simplify American spelling — but resistance kept most forms the same.
