Syntactic Structure

The hierarchical arrangement of elements in a programming language according to the language's grammar rules, including how statements, expressions, and blocks are nested and related to one another. In accessibility contexts, syntactic structure is significant because sighted programmers understand it primarily through visual cues like indentation, blank lines, and colour coding. Making this structural information available through non-visual means — such as aural rendering, haptic feedback, or structured navigation — is essential for enabling blind and visually impaired programmers to write and understand code effectively.
