error (n.)
also, through 18c., errour; c. 1300, "a deviation from truth made through ignorance or inadvertence, a mistake," also "offense against morality or justice; transgression, wrong-doing, sin;" from Old French error "mistake, flaw, defect, heresy," from Latin errorem (nominative error) "a wandering, straying, a going astray; meandering; doubt, uncertainty;" also "a figurative going astray, mistake," from errare "to wander; to err" (see err). From early 14c. as "state of believing or practicing what is false or heretical; false opinion or belief, heresy." From late 14c. as "deviation from what is normal; abnormality, aberration." From 1726 as "difference between observed value and true value."

Words for "error" in most Indo-European languages originally meant "wander, go astray" (for example Greek plane in the New Testament, Old Norse villa, Lithuanian klaida, Sanskrit bhrama-), but Irish has dearmad "error," from dermat "a forgetting."

peccadillo (n.)

"slight sin, petty crime or fault," 1590s (earlier in corrupt form peccadilian, 1520s), from Spanish pecadillo, diminutive of pecado "a sin," from Latin peccatum "a sin, fault, error," noun use of neuter past participle of peccare "to miss, mistake, make a mistake, do amiss; transgress, offend, be licentious, sin," a word of uncertain origin.

Watkins traces it to PIE *ped-ko-, suffixed form of *ped- "to walk, stumble, impair," from root *ped- "foot." But de Vaan is suspicious: "there is no reference to feet in the meaning of peccare. And to 'make a faux pas' ... would hardly be rendered by the word for 'foot', but rather by 'walking.' " He finds a derivation from the root *pet- "to fall" via *pet-ko- "a fall, error" to be "better semantically, but the addition of *-ko- to the bare root seems strange."

There is an apparent reference from c. 1200, of fish, perhaps meaning "to make furrows on the surface of the water," but it might be a mistake for play. Transferred sense of "traverse like a plow" is from 1580s. Related: Plowed; plowing.
