Calls is a versatile word, which means to make contact or to communicate with someone using telephones, messaging apps or voice calls. However, there are a few synonyms that can be used in place of 'calls' like dial, phone, contact, or ring up. They convey the same meaning but give an alternative way to express the act of reaching out to someone through electronic devices. Additionally, synonyms like summons, invites, beckon, and entice provide an alternative way to describe how someone 'calls' another person to come closer or to take action. These synonyms help to keep writing interesting and avoid repetition.
