What are non –verbal signals? Explain.

Texts contain non-verbal signs along with the verbal signs in conveying meaning. Non-verbal signs are certain style features, such as different fonts, bold print, underlining, or italics.

Layout features are also non-verbal signals.

 For example:

heading: The heading is seen usually printed at the top of a page in bold to indicate what is being discussed in a particular chapter, column, or section of a passage. 

title: It tells you what the theme of the text is in a nut shell. 

subheading: It divides a piece of writing into shorter sections giving more clarity to it.. 

photographs: are pictures related to an article or a text or the graphic representation of an event or incident. 

captions: are comments or catchy phrases on pictures related to a text

division into 

paragraphs: each paragraph is a unit and deals with one particular idea (see also the section on paragraphs overleaf) to visualize facts and figures presented in the text

figures, graphs, bar, bar charts, etc. can be added in order to emphasize on the details of the written material.
