foal
UK[fəʊl]US[foʊl]
n
a young horse, donkey, or related animal, especially one less than one year old.
v
to give birth to a foal.
Etymology
the word 'foal' has a remarkably stable lineage, tracing directly back to the proto-indo-european root pōl-, which denoted the young of an animal. this root evolved into the proto-germanic fulô, which then became old english fola. the modern english spelling 'foal' emerged in middle english, preserving the core meaning essentially unchanged for millennia. its journey exemplifies how a basic, concrete term for a young animal can remain linguistically conservative, bypassing the complex morphological segmentation seen in many latinate or greek-derived words.
Analysis
this word is a simplex form. it is a loanword from old english fola, from proto-germanic fulô, from proto-indo-european pōl- (young of an animal). its functional role is as a complete lexical root.
Examples
