The phrase "lending ear" typically means to listen attentively to someone. Its antonyms, or words with opposite meanings, may include "ignoring," "tuning out," "dismissing," "neglecting," or "shrugging off." If someone is not lending their ear, they may be displaying a lack of interest or empathy towards the speaker, or may be preoccupied with their own thoughts and concerns. It is important to remember the value of active listening and being present for those who wish to share their thoughts and feelings. By doing so, we can build stronger relationships, foster trust, and better understand the people in our lives.
