The phrase "for show" typically means something that is done or presented merely for appearance, rather than for any functional or practical purpose. Some synonyms for this term include "superficial," "shallow," "ostentatious," "pretentious," "showy," and "empty." These descriptors all imply a lack of substance or depth, and suggest that the person or thing in question is more interested in creating an impression than in truly engaging with the task at hand. Similarly, the phrase "all show and no substance" is often applied to situations or individuals who prioritize style over substance, or who emphasize appearances at the expense of meaningful action or achievement.
