An attribute grammar is a formal way to define attributes for the productions of a formal grammar, associating these attributes to values. The evaluation occurs in the nodes of the abstract syntax tree, when the language is processed by some parser or compiler.

Attribute may refer to:

• In philosophy, a property, or a conclusion of a characteristic of an entity or substance
• Attribute (research), a characteristic of an object (man, thing, etc.)
• In art, an object that identifies a figure, most commonly referring to objects held by saints (earlier, by pagan gods) – see emblem and saint symbolism
• grammatical modifier, in linguistics, a syntax unit, either a word, phrase or clause, that modifies a noun
• A deity's aspect; see Attributes of God, Attributes of God in Christianity, and Apophatic theology
• Attribute grammar, in formal computer languages
