Memory Aids
Mnemonic
The word 'knee' has a silent 'k', just like you don't use your 'k' (as in the letter) when you kneel.
Conceptual Metaphor
SUBMISSION IS BEING ON ONE'S KNEES (e.g., 'bring to one's knees'); INSTINCT/UNTHINKING REACTION IS A KNEE MOVEMENT (e.g., 'knee-jerk reaction').

Common Pitfalls
Translation Traps (for Russian speakers)
- The Russian word 'колено' (koleno) can mean 'knee', 'generation' (as in family line), or a 'verse' in a song. English 'knee' only refers to the body part or direct metaphors from it.
Common Mistakes
- Misspelling as 'nee' (which is a different word).
- Pronouncing the 'k' (hypercorrection).
- Confusing 'knee' (noun) with 'kneel' (verb).
