Semantic change (also semantic shift, semantic progression, semantic development, or semantic drift) is a form of language change regarding the evolution of word usage—usually to the point that the modern meaning is radically different from the original usage. In diachronic (or historical) linguistics, semantic change is a change in one of the meanings of a word. Every word has a variety of senses and connotations, which can be added, removed, or altered over time, often to the extent that cognates across space and time have very different meanings. The study of semantic change can be seen as part of etymology, onomasiology, semasiology, and semantics. Awful — Literally "full of awe", originally meant "inspiring wonder (or fear)", hence "impressive". In contemporary usage, the word means "extremely bad". Awesome — Literally "awe-inducing", originally meant "inspiring wonder (or fear)", hence "impressive". In contemporary usage, the word means "extremely good". Terrible — Originally meant "inspiring terror", shifted to indicate anything spectacular, then to something spectacularly bad. Terrific — Originally meant "inspiring terror", shifted to indicate anything spectacular, then to something spectacularly good. Nice — Originally meant "foolish, ignorant, frivolous, senseless." from Old French nice (12c.) meaning "careless, clumsy; weak; poor, needy; simple, stupid, silly, foolish," from Latin nescius ("ignorant or unaware"). Literally "not-knowing," from ne- "not" (from PIE root *ne- "not") + stem of scire "to know" (compare with science). "The sense development has been extraordinary, even for an adj." [Weekley] -- from "timid, faint-hearted" (pre-1300); to "fussy, fastidious" (late 14c.); to "dainty, delicate" (c. 1400); to "precise, careful" (1500s, preserved in such terms as a nice distinction and nice and early); to "agreeable, delightful" (1769); to "kind, thoughtful" (1830). Naïf or Naïve —Initially meant "natural, primitive, or native" . From French naïf, literally "native".

Onomasiology (from ὀνομάζω onomāzο 'to name', which in turn is from ὄνομα onoma 'name') is a branch of linguistics concerned with the question "how do you express X?" It is in fact most commonly understood as a branch of lexicology, the study of words (although some apply the term also to grammar and conversation). Onomasiology, as a part of lexicology, starts from a concept which is taken to be prior (i.e. an idea, an object, a quality, an activity etc.) and asks for its names.

A pejorative, slur, or derogatory term is a word or grammatical form expressing a negative or a disrespectful connotation, a low opinion, or a lack of respect toward someone or something. It is also used to express criticism, hostility, or disregard. Sometimes, a term is regarded as pejorative in some social or ethnic groups but not in others, or may be originally pejorative but later adopt a non-pejorative sense (or vice versa) in some or all contexts.

Lexicology is the branch of linguistics that analyzes the lexicon of a specific language. A word is the smallest meaningful unit of a language that can stand on its own, and is made up of small components called morphemes and even smaller elements known as phonemes, or distinguishing sounds. Lexicology examines every feature of a word – including formation, spelling, origin, usage, and definition. Lexicology also considers the relationships that exist between words.
