Morphology

control + character

The meaning 'a non-printing symbol used to control text interpretation' is directly derivable from combining 'control' (to regulate or manage) with 'character' (a symbol); the compound denotes a character that performs a controlling function. This noun–noun compositional pattern is common and appears similarly in other languages (e.g., Spanish 'carácter de control'), so a B1 learner who knows both constituents can reasonably infer the meaning.

Etymology

Control character comes from early computers and printers, where a character could be a visible letter or an invisible code and the control ones sent small commands like 'move to a new line' or 'tab'. So today a control character is an invisible symbol that tells a machine how to handle or show text.
