The Full Story
Proto-Germanicc. 500 BCE – 200 CEwell-attested
TheEnglishword 'foal' descends from Proto-Germanic *fulaz, the reconstructed form for a young horse or young of an equid. This root undergoes the systematic consonant shifts described by Grimm's Law: the PIE voiceless labial stop *p- shifts to Proto-Germanic *f-, a defining feature of the Germanic branch. The PIE source is *pōlo- or *pōlós, meaning 'young animal, foal', which is also the ancestor

The *p-* to *f-* shift that gave English 'foal' is the same consonant law that turned Latin *pater* into English *father* and Latin *piscis* into *fish*. Greek *pōlos* and Latin *pullus* — the ancestors of 'pullet' and 'poultry' — share the same PIE root *pōlH-* as 'foal', meaning the English words for a young horse and a young chicken are, at sufficient depth, the same word, diverged across millennia and two separate branches of the Indo-European family. The Norman French *poulain* that briefly
, where Christ's entry into Jerusalem references a colt (Old English 'fola'). The word appears in Old High German as 'folo', Old Saxon as 'folo', Old Norse as 'foli' (masculine), and Gothic as 'fula'. These parallel forms across the West and North Germanic branches confirm the reconstruction of *fulaz with high confidence.
The Verner's Law alternation is not prominently visible in this root, but the Grimm shift *p > *f is the key diagnostic marker separating Germanic from Latin (pullus) and Greek (pōlos). Semantically, the word has remained remarkably stable: throughout its attested history it denotes specifically a young horse (less than one year old), and this narrow zoological meaning persists into Modern English with no significant drift. Old Norse 'foli' appears in the Eddic corpus in contexts describing cavalry and the horse culture of the Norse world. The Old English 'fola' is glossed against Latin 'pullus equinus' in Anglo-Saxon glossaries such as the Corpus Glossary and the Épinal Glossary, providing some of the earliest direct attestations of the word. Key roots: *pōlo- (Proto-Indo-European: "young animal, foal; cognate with Greek pōlos and Latin pullus"), *fulaz (Proto-Germanic: "young horse; shows Grimm's Law shift *p > *f from PIE"), fola (Old English: "foal, young horse; masculine a-stem noun, attested in Anglo-Saxon glossaries").
