てごらん

てごらん is a casual, slightly playful imperative used to encourage someone to try or check something. It sounds softer than a direct order and is common among friends, family, or people of the same age. It can be used with verbs to invite someone to attempt an action (e.g., make an effort to do something) or to suggest that they look at or examine something. Because it is informal, you should avoid using it with strangers or in formal settings. The nuance is similar to saying “give it a try” or “have a look” in English, with a friendlier, supportive tone.
