Etymology
the modern english word "knife" originates from the old norse "knifr," meaning a blade or cutting instrument. this term replaced the old english word "cnif," showing the significant linguistic influence of the viking settlers in england. the ultimate origin is likely from the proto-germanic "knibaz," which is thought to be related to a root meaning "to pinch" or "to compress," conceptually linking to the action of cutting. the silent 'k' at the beginning is a vestige of its germanic ancestry, preserved in spelling but not in pronunciation.
Analysis
the word "knife" is a simplex word of old norse origin. it does not break down into smaller, meaningful morphemes within modern english spelling.
Examples
