To welcome someone means to greet them warmly and show them hospitality. Hence, the person is not being sent away but received with open arms. Finally, inviting is asking someone to come or join us, implying that the person is wanted and accepted. These antonyms show that "send away" carries negative connotations of rejection, dismissal, or exclusion. In contrast, the antonyms portray a positive and inclusive attitude towards people, advocating for retention, acceptance, and hospitality.
