Gayatri is, in the first instance, the name of a Vedic poetic meter, a fixed pattern of twenty four syllables arranged in three lines of eight, one of several meters used throughout the Rig Veda for hymns addressed to many different deities, not a term coined for this verse alone. This particular verse, however, became so overwhelmingly the best known example of the meter that gayatri in ordinary usage now refers to the verse itself rather than to the metrical form it happens to share with a great many other, far less famous, Vedic compositions, a case of a specific instance of a category eclipsing the category's own name in common usage.
As a hymn rather than as an extracted mantra, this verse belongs to a longer sukta, Rig Veda 3.62, addressed across several verses to Savitr, the aspect of the solar deity specifically associated with impelling or setting things in motion, rather than to the sun considered generally, and the sukta as a whole belongs to the family book tradition associated with the seer Vishvamitra. The larger hymn situates this one verse within a sequence of related solar invocation rather than presenting it as an isolated composition, and Vedic ritual practice historically recited it as part of the morning and evening sandhya rites performed by twice born Hindus, timed specifically to the transitions of dawn and dusk that Savitr, as the impelling solar power, was understood to govern, a liturgical timing that gives the verse's placement within its daily ritual use a coherence the extracted, standalone mantra version discussed elsewhere in this atlas does not by itself convey.
