The operation of deducing one function from another according to some fixed law, called the law of derivation, as the of differentiation or of integration
The act of receiving anything from a source; the act of procuring an effect from a cause, means, or condition, as profits from capital, conclusions or opinions from evidence
The components or etymology of the entry For an entry such as `lu2 kur2', this will contain both `lu2' and `kur2', thus enabling the entry to be automatically listed under both lu2 and kur2 in the appropriate usage sections The elements and origins attributes consist of two parallel sequences of IDREF's, the elements IDREF's refer to the ID field of other entry articles if the corresponding origins attribute is PSD This is the primary intended use for this field in PSD Otherwise, the element IDREF will refer to an ID constructed in a list of foreign terms, and the origins IDREF will refer to the originating language Since multiple suggestions are often possible for the origin of a term, and not all are certain, the derivation field may be repeated, and also takes an attribute indicating whether the derivation is considered certain (certain="y") or questionable (certain="n")
The operation of deducing one function from another according to some fixed law, called the law of derivation, as the operation of differentiation or of integration
Word formation process in which an affix that is not an inflection is attached to a stem or base word Derivation changes the meaning of the word or its part of speech classification E g , manly produces an adjective from a noun; unmanly negates the meaning of manly
The derivation of something, especially a word, is its origin or source. The derivation of its name is obscure = origin. the origin of something, especially a word
{i} source, origin; something that has been derived; act of deriving; (Grammar) process of making new words from a root word (ex: "painting from the word "paint")
The process by which words are formed from existing words or bases by adding affixes, as singer from sing or undo from do, by changing the shape of the word or base, as song from sing, or by adding an affix and changing the pronunciation of the word or base, as electricity from electric A linguistic description of the process of word formation
drawing off water from its main channel as for irrigation drawing of fluid or inflammation away from a diseased part of the body a line of reasoning that shows how a conclusion follows logically from accepted propositions the source from which something derives i
comes or issues); "he prefers shoes of Italian derivation" (descriptive linguistics) the process whereby new words are formed from existing words or bases by affixation: `singer' from `sing'; `undo' from `do'
A derivation of a sentence of a grammar is, in effect, a proof that the sentence can be derived from the start symbol of the grammar using the grammar rules and a rewriting process For example, given the grammar 1 S -> NP VP, 2 NP -> ART N, 3 VP -> V, and lexical rules 4 ART -> "the", 5 N -> "cat", and 6 V -> "miaowed", we can derive the sentence "the cat miaowed" as follows: S=>NP VPrule 1 =>ART N VPrule 2 =>the N VPrule 4 =>the cat VPrule 5 =>the cat Vrule 3 =>the cat miaowedrule 6 One can then write S =>* "the cat miaowed": i e =>* is the symbol for the derivation relation The symbol => is referred to as direct derivation
A finite, non-empty sequence of wffs in which the last member is the wff derived, and each of the others (the premises) is either an axiom, a member of a set of accepted premises, or the result of applying a rule of inference to wffs preceding it in the sequence See corresponding argument; proof Notation: A (the wff A can be derived from the set of wffs )
