paddock

The noun is almost certainly a variant of dialectal British parrock (“enclosure; park; croft, small field, paddock”), from Middle English parrok, parrock (“enclosed pasture, paddock; coop; feeding stall; cabin, hut”) [and other forms], from Old English pearroc, pearruc (“fence used to enclose a space; area enclosed by such a fence, enclosure”), from Proto-West Germanic parruk (“enclosure; pen for animals”), from Proto-Germanic parrukaz (“fence; enclosure”); further etymology uncertain, perhaps related to Proto-Germanic barō (“bar, beam; barrier”), possibly from Proto-Indo-European bʰerH- (“to pierce; to strike”). Equivalent to park + -ock. Doublet of park. The verb is derived from the noun. Cognates * Danish park (“pond”) * Dutch perk (“flowerbed; garden; pen”) * German Pferch (“sheepfold, sheep-pen”)

From Middle English paddok, paddoke (“frog; toad”) [and other forms], from pad, pade (“frog; toad”) + -ok (diminutive suffix). Pad, pade is derived from Old English pada, padda, padde, from Proto-West Germanic paddā, from Proto-Germanic paddǭ (“toad”); further etymology uncertain, possibly ultimately from Proto-Indo-European *bʰew- (“to swell”). The English word is analysable as pad (“(Britain, dialectal) frog; toad”) + -ock (suffix forming nouns, originally with diminutive senses). Sense 2 (“sledge”) is probably from the supposed resemblance of the object to a frog or toad.
