μεταξύ

Etymology: From Ancient Greek μεταξύ (metaxú), which was formed from μετά (metá, 'in the middle, between') + ξύν (xún, 'with'). The word has maintained its meaning of indicating position or relationship between two or more things throughout its history. The prefix 'meta-' appears in many English words like 'metaphor', 'metamorphosis', and 'metabolism', all conveying a sense of change, transition, or being in the middle of something.
