The Spanish word 'albañil' (meaning 'mason' or 'builder') comes from Andalusi Arabic 'albanní' meaning 'builder', which in turn derives from Classical Arabic 'bannāʾ' (builder) with the Arabic definite article 'al-' (the) attached to it. This is one of many Spanish words that begins with 'al-', a telltale sign of Arabic origin, as this prefix was the Arabic definite article that became permanently attached to many words as they were borrowed into Spanish during the centuries of Muslim rule in medieval Spain.

While 'albañil' itself is a common Spanish word, there aren't many simpler or more common Spanish words that share its specific Arabic etymology. However, Spanish learners might notice that many other Spanish words beginning with 'al-' (like 'alcalde', 'almohada', 'alfombra') also come from Arabic, though they aren't directly related to 'albañil'.

There aren't any common English words directly related to 'albañil' since it comes from Arabic rather than the Latin or Germanic roots that English typically shares with Spanish. However, English speakers might find it interesting that the English word 'banner' comes from a different Medieval Latin word 'bandum' (flag), and is not related to the Arabic root of 'albañil' despite their slight similarity in sound.
