pset5 spellcheck, problem with load

Question

Could someone please review this code as I am not sure why am I getting segmentation fault while trying to use ' in words in a dictionary. I am attaching the code of my load function.

/////////////////////////////////////////////////// usefeull.h :

#include <stdbool.h>

typedef struct tries 
{
    bool end_Word;
    struct tries* children[27];
}
tries;
//////////////////////////////////////////////////
bool load(const char* dictionary)
{

 tries* root;

    //open file for reading
    FILE *dict = fopen(dictionary,"r");
    if(dict == NULL)
    {
        printf("Could not open file!!");
        unload();
        return false;
    }
   int letterIndex = 0;

    root = malloc(sizeof(root));
    tries* newL = root;

    int word = 0;
    //go through every single character of every single word in the dictionary

for(int c = fgetc(dict); c != EOF; c = fgetc(dict))
{

     //setting Index
     letterIndex = 55; 

        //check if the character is valid

            //set the letter index
     //setting index for ' char
     if (c == 39)
     {
        letterIndex = 26;
     }
    //getting index of alphanumeric char
    if (isalpha(c))
     {
        letterIndex = (c - 97) & 25;

     }

        //allocate memory for every node

        //if index not changed , new word and reset to the root
    if(letterIndex == 55)
    {

        word++;
        printf("%d\n" , word);
        newL -> end_Word = true; 
        newL = root;

    }
    //if letter found
    //if pointing to NULL
    else if(newL->children[letterIndex] == NULL)
    {

        newL-> children[letterIndex] = malloc(sizeof(newL));
        newL = newL->children[letterIndex]; 
        printf("being created\n");
    }
    //if already pointing 
    else 
    {
        newL = newL -> children[letterIndex];
        printf("position already exist\n");
    }
}

   return true;
}
