'Knave' is a dishonest person or rogue (archaic), or the jack in a pack of cards; 'nave' is the central hall of a church.
Noun. In archaic/literary English: a dishonest man or rogue. In playing cards (British usage): the jack. Appears frequently in Shakespeare and medieval texts.
The villain was described as a knavish rogue with a smile that could not be trusted.
In Shakespeare, the knave is often a clever servant who outwits his master.
The knave of hearts featured in the trial scene of Alice in Wonderland.
Noun. The central hall of a church where the congregation sits, between the entrance and the chancel. Also: the central hub of a wheel.
The Gothic cathedral had a soaring nave lined with carved stone pillars.
Wedding guests filled every seat along the nave before the ceremony began.
The nave of a wheel is the central hub through which the axle passes.
Common mistake
"The knave of the church" when meaning the hall (correct: nave). Or "She walked down the nave of hearts" when meaning the card (correct: knave). These are uncommon words confused by the silent K.
Trick to remember it
'Knave' has silent K like 'knight', 'kneel', 'knife' — the K is hidden, like the knave's dishonest intentions. 'Nave' has no K — open and honest like the church.
Quick rule
Is it the rogue or the card jack? 'Knave'. Is it the church's central hall? 'Nave'.
Did you know?
Playing cards originally called the face card below queen the 'knave' (from Old English 'cnafa' meaning boy or servant). The switch to 'jack' happened in the mid-19th century to avoid confusion with 'K' for King — both were abbreviated 'Kn' and 'K'. 'Nave' comes from Latin 'navis' (ship) — medieval church architects designed the high-ceilinged nave to resemble an upturned ship hull. The same root gives 'navy', 'naval', 'navigate', and 'navel' (the centre, like a hub).
