noun SPEEN Rare
Origin: Borrowed directly from English spin, from physics terminology.
Usage Note
Spin is an English loanword used unchanged in Spanish physics and chemistry texts to describe the intrinsic angular momentum of a particle. It is a masculine noun: el spin. Learners should note that Spanish texts use espín as a fully hispanicised alternative that follows Spanish phonology and spelling rules, although spin dominates in practice.
