The Spanish word 'arancel' (meaning 'tariff' or 'duty') has an interesting origin in Arabic. It comes from the Andalusi Arabic term 'al-inzál', which specifically referred to a 'lodging tax'. This term itself developed from Classical Arabic 'inzal', which simply meant 'lodging'. The evolution of meaning from 'lodging' to 'lodging tax' and finally to the more general concept of 'tariff' or 'duty' shows how the word's meaning expanded over time to encompass broader types of fees and charges.

Unlike many other Spanish words of Arabic origin, 'arancel' doesn't have many commonly used related words in modern Spanish. This might be because it entered Spanish as a specialized administrative or economic term.

There aren't any common English words directly related to 'arancel', as it comes from Arabic rather than the Latin or Germanic roots that English and Spanish often share. However, English speakers might find it helpful to associate 'arancel' with English words like 'tariff' or 'duty' which have the same meaning, even though they're not etymologically related.
