'Night' is the period of darkness; 'knight' is a medieval armoured warrior or a chess piece.
Noun. The period of darkness between sunset and sunrise.
We worked through the night to meet the deadline.
The city looks beautiful at night when all the lights come on.
She stayed up all night studying for the certification exam.
Noun. A medieval armoured soldier of noble rank. Also the chess piece that moves in an L-shape. In the UK, an honorary title (Sir).
The knight wore heavy armour and rode into battle on horseback.
In chess, the knight is the only piece that can jump over others.
Sir Paul McCartney was made a knight by Queen Elizabeth in 1997.
Common mistake
The main issue is the silent K in 'knight' — learners often spell it 'nite' or 'nigt'. Also confusing 'goodnight' (one word, farewell) with 'good night' (two words, literal time of day).
Trick to remember it
'Knight' belongs to the KN family: know, kneel, knock, knife, knob, knit — all with a silent K. Old English pronounced this K as /kn/, but it silenced over centuries. 'Night' is simpler — dark + time, no silent letters beyond the GH.
Quick rule
Is it the darkness of the night? 'Night'. Is it the armoured warrior or chess piece? 'Knight'.
Did you know?
In chess, the piece is called 'knight' in English but 'horse' or 'rider' in virtually every other language (caballo in Spanish, cheval in French, Springer in German, конь in Russian). English chess terminology reflects the medieval chivalric tradition — the piece represents a mounted knight, not just any horse. The KN spelling in 'knight' survives from Old English where kn- was pronounced as a consonant cluster.
