Final answer:
Technical language is specialized vocabulary used by professionals within a specific field to communicate effectively with others in the same field, as described in option A.) 'It is typically used by professionals in a specialized field.'
Step-by-step explanation:
Technical language refers to the specialized vocabulary used by professionals within a particular field to communicate succinctly and accurately with one another. This vernacular contains terms, concepts, and jargon that are not commonly understood by the general public, making its use in broader audiences less effective. For instance, in the context of visual rhetoric, terms like 'line', 'light', and 'point of view' represent particular technical language. These phrases allow for precise and efficient communication among experts who share an understanding of these concepts' complexities, which might be opaque to laypersons.
Hence, technical language showcases a level of mastery and familiarity within a discipline that aids in specialized discourse. Contrastingly, figurative language, which includes metaphors and similes, serves a different communicative purpose by invoking imaginative comparisons to evoke sensory experiences or emotions. Such language deviates from the literal interpretation to enrich the text with depth and color, which is quite the opposite of straightforward, context-specific technical language. Given these nuances, it is clear that option A.) 'It is typically used by professionals in a specialized field.' best describes technical language.
