  (file)

• Rhymes: -ake
• Syllabification: ja‧que

Inherited from Old Spanish xaque, from Arabic شاه (šāh, “shah; king chess piece”), from Middle Persian 𐭬𐭫𐭪𐭠 (mlkʾ /⁠šāh⁠/, “king”). Doublet of cheque and escaque (“chess tile”), the latter formerly meaning "(any) chess piece" as well.

To explain the unusual rendering of Arabic -h as /k/ (-que), Coromines and Pascual suggest influence from escaque instead. They also mention an alternative idea they find less likely where the sound [h] was exaggerated as [k], cf. Medieval Latin nichil [ˈnikil]. Yet another explanation (not in Coromines and Pascual) for the /k/ is that it is from Arabic شاهك šāh-ak ("your king"), especially as it is used to announce an upcoming attack onto the enemy's king. First attested in 1283 as dar xaque ("to threaten the enemy's king").
