Synonym study

2. Bad, evil, ill, wicked are closest in meaning in reference to that which is lacking in moral qualities or is actually vicious and reprehensible. Bad is the broadest and simplest term: a bad man; bad habits. Evil applies to that which violates or leads to the violation of moral law: evil practices. Ill now appears mainly in certain fixed expressions, with a milder implication than that in evil: ill will; ill-natured. Wicked implies willful and determined doing of what is very wrong: a wicked plan.

Usage note

The adjective bad meaning “unpleasant, unattractive, unfavorable, spoiled, etc.,” is the usual form to follow such copulative verbs as sound, smell, look, and taste: After the rainstorm the water tasted bad. The coach says the locker room smells bad. After the copulative verb feel, the adjective badly in reference to physical or emotional states is also used and is standard, although bad is more common in formal writing: I feel bad from overeating. She felt badly about her friend's misfortune.
When the adverbial use is required, badly is standard with all verbs: She reacted badly to the criticism. Bad as an adverb appears mainly in informal contexts: I didn't do too bad on the tests. He wants money so bad it hurts. See also badly, good.

Word Origin and History for my bad

bad

adj.

c.1200, "inferior in quality;" early 13c., "wicked, evil, vicious," a mystery word with no apparent relatives in other languages.* Possibly from Old English derogatory term bæddel and its diminutive bædling "effeminate man, hermaphrodite, pederast," probably related to bædan "to defile." A rare word before 1400, and evil was more common in this sense until c.1700. Meaning "uncomfortable, sorry" is 1839, American English colloquial.

Comparable words in the other Indo-European languages tend to have grown from descriptions of specific qualities, such as "ugly," "defective," "weak," "faithless," "impudent," "crooked," "filthy" (e.g. Greek kakos, probably from the word for "excrement;" Russian plochoj, related to Old Church Slavonic plachu "wavering, timid;" Persian gast, Old Persian gasta-, related to gand "stench;" German schlecht, originally "level, straight, smooth," whence "simple, ordinary," then "bad").

Comparative and superlative forms badder, baddest were common 14c.-18c. and used as recently as Defoe (but not by Shakespeare), but yielded to comparative worse and superlative worst (which had belonged to evil and ill).

As a noun, late 14c., "evil, wickedness." In U.S. place names, sometimes translating native terms meaning "supernaturally dangerous." Ironic use as a word of approval is said to be at least since 1890s orally, originally in Black English, emerging in print 1928 in a jazz context. It might have emerged from the ambivalence of expressions like bad nigger, used as a term of reproach by whites, but among blacks sometimes representing one who stood up to injustice, but in the U.S. West bad man also had a certain ambivalence:

These are the men who do most of the killing in frontier communities, yet it is a noteworthy fact that the men who are killed generally deserve their fate. [Farmer & Henley]

*Farsi has bad in more or less the same sense as the English word, but this is regarded by linguists as a coincidence. The forms of the words diverge as they are traced back in time (Farsi bad comes from Middle Persian vat), and such accidental convergences exist across many languages, given the vast number of words in each and the limited range of sounds humans can make to signify them. Among other coincidental matches with English are Korean mani "many," Chinese pei "pay," Nahuatl (Aztecan) huel "well," Maya hol "hole."
