In common usage, the prefix dipolar, dative or coordinate merely serves to indicate the origin of the electrons used in creating the bond. For example, F 3 B ← O(C 2 H 5) 2 ("boron trifluoride (diethyl) etherate") is prepared from BF 3 and :O(C 2 H 5) 2, as opposed to the radical species [•BF 3] – and [•O(C 2 H 5) 2] +.
"Dative" comes from Latin cāsus datīvus ("case for giving"), a translation of Greek δοτικὴ πτῶσις, dotikē ptôsis ("inflection for giving"). [2] Dionysius Thrax in his Art of Grammar also refers to it as epistaltikḗ "for sending (a letter)", [3] from the verb epistéllō "send to", a word from the same root as epistle.
The vector component or vector resolute of a perpendicular to b, sometimes also called the vector rejection of a from b (denoted or a ⊥b), [1] is the orthogonal projection of a onto the plane (or, in general, hyperplane) that is orthogonal to b.
Course in General Linguistics (French: Cours de linguistique générale) is a book compiled by Charles Bally and Albert Sechehaye from notes on lectures given by historical-comparative linguist Ferdinand de Saussure at the University of Geneva between 1906 and 1911.
The oxygen molecule, O 2 can also be regarded as having two 3-electron bonds and one 2-electron bond, which accounts for its paramagnetism and its formal bond order of 2. [14] Chlorine dioxide and its heavier analogues bromine dioxide and iodine dioxide also contain three-electron bonds. Molecules with odd-electron bonds are usually highly ...
In Latin grammar, a double dative is the combination of a dative of reference with a dative of purpose.A common translation is "As a (dative of purpose) with reference to (dative of reference)."

In cryptography, an initialization vector (IV) or starting variable [1] is an input to a cryptographic primitive being used to provide the initial state. The IV is typically required to be random or pseudorandom, but sometimes an IV only needs to be unpredictable or unique.
