_Purlieu_ (Vol. vii., p. 477.).--The etymology of this word which Dr.
Johnson adopted is that which many others have approved of. The only other
derivation which appears to have been suggested is from _perambulatio_.
Blount, _Law Dict._, s. voc., thus explains:
"_Purlue_ or _Purlieu_ (from the Fr. _pur_, i. e. _purus_, and _lieu_,
locus) is all that ground near any forest, which being made forest by
Henry II., Richard I., or King John, were, by _perambulation_, granted
by Henry III., severed again from the same, and became _purlue_, i. e.
pure and free from the laws and ordinances of the forest. Manwood, par.
2., For. Laws, cap. 20.; see the statute 33 Edw. I. stat. 5. And the
perambulation, whereby the _purlieu_ is deafforested, is called
_pourallee_, i. e. _perambulatio_. 4 Inst. fol. 303."
