Antonyms for "lighting on" include "missing," "avoiding," and "evading." When someone fails to "light on" an object or misses their intended target, it can signify a lack of precision, accuracy, or focus. It's not uncommon for athletes, hunters, or marksmen to aim for a target and miss, or for someone looking for a particular item to search in vain. However, missing can also be intentional, as in when someone wants to avoid a certain location or person. For example, a person may deliberately miss a party or event if they dislike the host or guests. Ultimately, the opposite of "lighting on" hinges on one's ability, motivation, and willingness to focus on a task or aim for a goal.
