Kashida

Kashida (Persian: کشیده‎; "extended", "stretched", "lengthened") is a type of justification used in some cursive scripts related to Arabic[citation needed]. In contrast to white-space justification, which increases the length of a line of text by expanding spaces between words or individual letters, kashida justification is accomplished by elongating characters at certain chosen points. Kashida justification can be combined with white-space justification to various extents.

The analog in European (Latin-based) typography (expanding or contracting letters to improve spacing) is sometimes called expansion, and falls within microtypography. Kashida is considerably easier and more flexible, however, because Arabic-Persian scripts feature prominent horizontal strokes, whose length is accordingly flexible.

For example, alħamdu and Raħīm with and without kashida may look like the following:

Word Meaning Normal Kashida
alħamdu ‘the praise’ الحمد الحمــــــد
Raħīm a male name رحيم رحــــــيم

Kashida can also refer to a character representing this elongation (ـ) – also known as tatweel or taṭwīl (تطويل taṭwīl) – or to one of a set of glyphs of varying lengths that are used to implement this elongation in a font. The Unicode standard assigns codepoint U+0640 as "Arabic Tatweel".

The right side of this basmala contains a long kashida with a natural curve.

The kashida can take a subtle downward curvature in some calligraphic styles and handwriting. However, the curvilinear stroke is not feasible for most basic fonts, which merely use a completely flat underscore-like stroke for kashida.

In addition to letter spacing and justification, kashida is also used for emphasis and as book or chapter titles.

Kashida is generally only be used in one word per line and applied to one letter per word. Furthermore, kashida is recommended only between certain combinations of letters. Some calligraphers – paid by the number of pages produced – used an inordinate amount of kashida in order to stretch the contents over more pages.[1]
