'''Polarity''' is a relation between two opposite attributes or tendencies; "he viewed it as a balanced polarity between [[Goodness|good]] and [[evil]]"
mutual opposition, oppositeness, opposition - the relation between opposed entities. It can also refer to having an indicated pole (as the distinction between positive and negative electric charges); "he got the polarity of the battery reversed"; "charges of opposite sign"

==Linguistic==
'''Grammatical polarity''' is the distinction of affirmative and negative, which indicates the [[truth]] or falsehood of a statement respectively. In [[English]], grammatical polarity is generally indicated by the [[presence]] or absence of the modifier ''not'', which negates the statement. Many other [[language]]s contain similar modifiers: Italian and Interlingua have ''non'', Spanish has ''no'', French has ''ne ... pas'', German has ''nicht'', and Swedish has ''inte''.
==Physics==
'''Polarity''' is a description of an attribute, typically a binary attribute (one with two values), or a [[vector]] (a direction). For example:
* An electric charge has a polarity of either positive or negative.
* A voltage has a polarity, in that it could be positive or negative (with respect to some other voltage, such as the one at the other end of a battery or electric [[Circuitry|circuit]]).
* A [[magnet]] has a polarity, in that one end is the "north" and the other is the "south".
* The spin of an entity in [[quantum mechanics]] has a polarity - positive or negative.
* Polarized [[light]] has waves which all line up in the same direction.
Chemical polarity is a feature of [[Chemistry|chemical bond]]s, where two different [[atom]]s in the same [[molecule]] have different electronegativity. As a result, the electrons in the bond are not shared equally by the two atoms. This causes an asymmetrical (polar) electric field. Molecular covalent bonds can be described as polar or nonpolar. Entire molecules can also be described as polar.
