Access value of a pointer in dynamically allocated memory

My assignment is to read words from a text file and store them in character arrays which are stored in an array of char*. All memory in these arrays needs to be dynamically allocated.

What I am doing is reading in each word with fscanf() and storing it into the variable str. I am then calculating the length of the word in str and dynamically allocating memory to store the value of str in the character array new_word. new_word is then inserted into the array of char* named words. When words runs out of space, I double its size and continue.

My problem lies in the commented code starting on line 62. I'm going to need to read these words later from words, so I'm testing my ability to access the pointers and their values. I can index new_word fine (in the lines above), but when I then store new_word in words and try to read from words, I get the following error:

hw1.c:63:25: error: subscripted value is not an array, pointer, or vector while (*(words[count])[k] != '\0'){

on lines 63 and 64. I know it has something to do with dereferencing the pointer, but I have tried a bunch of variations with no success. How can I fix this?

Here is the code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>


int main(int argc, char* argv[]){

    if (argc != 3){
        fprintf(stderr, "Incorrect number of arguments\n");
        exit(1);
    }

    char* infile = argv[1];
    FILE* finp = fopen(infile, "r");
    if (finp == NULL){
        fprintf(stderr, "Unable to open input file\n");
        exit(1);
    }

    char* prefix = argv[2];

    int count = 0;
    int size = 20;
    char* words = calloc(size, sizeof(char));
    printf("Allocated initial array of 20 character pointers.\n");
    char* str = malloc(30*sizeof(char));

    while (fscanf(finp, "%s", str) == 1){

        if (count == size){
            words = realloc(words, 2 * size);
            size *= 2;
            printf("Reallocated array of %d character pointers.\n", size);
        }

        int i = 0;
        while (str[i] != '\0'){
            i++;
        }

        char* new_word = malloc((i+1)*sizeof(char));

        int j = 0;
        while (str[j] != '\0'){
            new_word[j] = str[j];
            j++;
        }

        new_word[j] = '\0';

        int k = 0;

        while (new_word[k] != '\0'){
            printf("%c", new_word[k]);
            k++;
        }

        printf("\n");

        words[count] = *new_word;

        /*k = 0;
        while (*(words[count])[k] != '\0'){
            printf("%c", *(words[count])[k]);
            k++;
        }

        printf("\n");*/

        count++;

    }
