Much of Tamil grammar is extensively described in the oldest available grammar book for Tamil, the Tolkāppiyam (dated between 300 BCE and 300 CE). Modern Tamil writing is largely based on the 13th century grammar Naṉṉūl , which restated and clarified the rules of the Tolkāppiyam with some modifications.
Extended-Tamil script or Tamil-Grantha refers to a script used to write the Tamil language before the 20th century Tamil purist movement. [1] Tamil-Grantha is a mixed-script: a combination of the conservative-Tamil script that independently evolved from pre-Pallava script, combined with consonants imported from a later-stage evolved Grantha script (from Pallava-Grantha) to write non-Tamil ...
Example of Manipravalam text converted to Tamil language and script. It is suggested that the advent of the Manipravalam style, where letters of the Grantha script coexisted with the traditional Vatteluttu letters, made it easier for people in Kerala to accept a Grantha-based script Ārya eḻuttŭ, and paved the way for the introduction of the new writing system.

Modern Tamil writing is largely based on the 13th-century grammar Naṉṉūl which restated and clarified the rules of the Tolkāppiyam, with some modifications. Traditional Tamil grammar consists of five parts, namely eḻuttu, col, poruḷ, yāppu, aṇi. Of these, the last two are mostly applied in poetry. [104]
The Tamil script (தமிழ் அரிச்சுவடி Tamiḻ ariccuvaṭi [tamiɻ ˈaɾitːɕuʋaɽi]) is an abugida script that is used by Tamils and Tamil speakers in India, Sri Lanka, Malaysia, Singapore and elsewhere to write the Tamil language. [5] It is one of the official scripts of the Indian Republic.
Naṉṉūl (Tamil: நன்னூல்) is a work on Tamil grammar written by a Jain ascetic [1] Pavananthi Munivar around 13th century CE. [2] It is the most significant work on Tamil grammar after Tolkāppiyam. [2] The work credits Western Ganga vassal king Seeya Gangan of Kolar with patronising it. [3] [4]
The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal or its tangent. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper ...
The gradient of F is then normal to the hypersurface. Similarly, an affine algebraic hypersurface may be defined by an equation F(x 1, ..., x n) = 0, where F is a polynomial. The gradient of F is zero at a singular point of the hypersurface (this is the definition of a singular point). At a non-singular point, it is a nonzero normal vector.
