The Spanish word 'arrobamiento', meaning 'rapture' or 'ecstasy', has an interesting etymology that traces back to Arabic. It starts with the Arabic word 'ar-rub'' (الربع), meaning 'quarter'. This entered Spanish as 'arroba', which was a unit of weight measurement.

From 'arroba', the verb 'arrobar' was derived, meaning 'to enrapture' or 'to entrance'. The shift in meaning from a weight measure to an emotional state might be related to the idea of being 'weighed down' or 'overwhelmed' by emotion. Finally, the noun 'arrobamiento' was formed by adding the common Spanish suffix '-miento' (which forms nouns indicating an action or its result) to the verb 'arrobar'.

A simpler and more common Spanish word that shares this etymology is 'arroba' (@), which today is most famously known as the symbol used in email addresses and social media handles. This word still maintains its connection to the original Arabic meaning of 'quarter', as historically it represented a weight measure of approximately 25 pounds (a quarter of a hundredweight). The verb 'arrobar' is also related but less commonly used.

While there aren't direct English cognates from this Arabic-derived word family, English speakers might be familiar with the '@' symbol (called 'arroba' in Spanish) from email addresses and social media handles. This connection, though not etymological, can help English speakers remember the Spanish word family.
