Command language refers to the syntax used to give instructions to a computer or electronic device. Antonyms for this phrase can include informal language, non-technical language, or plain language. These phrases refer to language that uses a more conversational tone, eschewing technical jargon and complex syntax. This approach is often used to bridge the communication gap between technical experts and non-experts. By using plain language, instructions can be conveyed in a way that is easier for everyone to understand, increasing accessibility and reducing mistakes. So, while a command language may be necessary for certain tasks, using plain language can be helpful in many situations.
