ETYMOLOGY
from Latin pigritia (laziness, sluggishness, sloth) + -ous
EXAMPLE
“… Now if Stercus and Ʋrina can bee pickt out of the vanities of Cornelius Agrippa, it shal be thrown upon the purple robes of the Physician, by the ignorant or impudent. For Science hath no enemy but ignorance, nor is vilified among any except pigritious and impudent persons. Then let the ignorant prattle, still the Physitian shall be the instrument of all common good in a Republique, and if no valetudinarie man of any condition bee able to effect any solid good, either to his King, Countrie, or selfe, as he is not, and the power of restoring and healing him, bee given principally to the Phisician …”
