How i can fix this code? i need to cancel a node and return next node with 2 equal string?

NodePtr cancWord(NodePtr head, char *vett){
if(!head)
return NULL;

    if(strcmp(head->word,vett)==0){
        NodePtr tmp = head;
        head = head->next;
        free(tmp->word);
        free(tmp);
        return head;
    }
    head->next = cancWord(head->next,vett);
    
    return head;

}
