The Spanish for “equal”, par, has a few useful parallels in English. All — in Spanish and English — come from the same Latin root par meaning “equal”.
- Pair – A pair is really two equals together, literally.
- Peer – Your peer is someone who is your equal, or at least at an equal level to you.
- Disparage – is literally to note that someone is not your equal, with the dis- negative prefix before the p-r root.
In all of these, we can see the p-r mapping consistently and easily.
