The Spanish word 'barquilla' meaning 'small boat' comes from the Spanish word 'barca' (meaning 'boat') combined with the diminutive suffix '-illa'. The Spanish 'barca' itself derives from the Latin word 'barca', also meaning 'boat'. The diminutive suffix '-illa' is commonly used in Spanish to indicate something is small or cute, so 'barquilla' literally means 'little boat'.
