A literal can also be classified as vocal or consonantal depending on whether it can be pronounced independently or not. Concept of literals is closely linked to fonts or some code for information interchange in general. Whether a character sequence has a single fused graphical form or not, can be decided only by analysing that code. It can also be interpreted as a sequence of literals and symbols represented by that character stream. In our description, source script is Malayalam and target script is English.

There are two different contexts for a literal. One is the lexical context and other is the phonetical context. By default context means phonetical context. A literal can have null neighbourhood also. That is, when no other sound is pronounced along with it.
