Origin
Dandelion entered English in the fifteenth century from Old French 'dent de lion' (tooth of the lion), itself a translation of Medieval Latin 'dens leonis', coined by herbalists who saw the jagged leaves as lion's fangs — connecting the garden weed to Latin 'dens', tooth, and ultimately to the same Proto-Indo-European root as the English word 'tooth'.

The Full Story
Old FrenchMedieval, c. 1300–1500well-attested
The word 'dandelion' is a direct anglicisation of the Old French phrase 'dent de lion', meaning 'tooth of the lion', a vivid metaphor for the plant's deeply serrated, tooth-edged leaves. The plant (Taraxacum officinale) was identified in medieval European herbal tradition primarily by these jagged leaf margins, which were likened to a lion's teeth. The Latinscholarlyname

Theword 'indenture' — a legalcontract — is a direct relative of 'dandelion'. Medieval contracts were written in duplicate on a single sheet, then cut apart with a jagged, tooth-like edge; the two halves could later be matched to prove authenticity. The Latin 'indentare' meant to cut with teeth, from 'dens', the same
to Proto-Indo-European *h₁dónts (tooth), a participial form of the root *h₁ed- (to eat, to bite). This same PIE root yields English 'tooth' (via Germanic *tanþuz), Greek 'odous/odontos' (whence 'orthodontics', 'odontology'), Sanskrit 'danta', and Welsh 'dant'. Interestingly, other European vernaculars preserve different folk names. French retains 'pissenlit' (piss-in-bed), a reference to the plant's diuretic properties. German uses 'Löwenzahn' (lion's tooth), a direct calque of the Latin/French. Dutch has 'paardenbloem' (horse flower). These parallel naming traditions show that the 'tooth of the lion' metaphor was the learned, herbal tradition's label, while folk names often reflected medicinal uses. Key roots: *h₁dónts (Proto-Indo-European: "tooth; biting one; participle of *h₁ed- (to eat, to bite) — cognates include Latin dens, Greek odous, Sanskrit danta, English tooth, Gothic tunþus"), dens, dentis (Classical Latin: "tooth — source of English dental, dentist, indent, trident, dandelion"), *lewk- (Proto-Indo-European: "light, brightness — ancestral root of Latin lux, lucere, and possibly underlying the name 'lion' via a separate lineage through Greek leon").
