The Mystery of the Silent 'K' in 'Knife': Unraveling English Language History

• The 'K' in words like 'Knife', 'Know', and 'Knee' is a silent letter, meaning it's written but not pronounced.
• Historically, around 1000-1500 AD, the 'K' in these words was fully pronounced, reflecting their Old English and Germanic roots.
• The 'Great Vowel Shift' in the 16th-17th centuries led to changes in pronunciation, making the 'Kn' cluster difficult to articulate.
• French linguistic influence, which avoided such consonant clusters, and the 'Principle of Least Effort' also contributed to the 'K' becoming silent.
• The invention of the printing press solidified spellings, preserving the 'K' in writing even as its pronunciation faded.

Why It Matters: The silent 'K' in 'Knife' is a historical relic, showcasing centuries of English language evolution.
