When iterating through a list using zip with a break statement it returns every second value

Question

with open("dict_data.txt") as f:
    word_list = [i.replace("\n","").lower() for i in f.readlines()]

possible_words = word_list
search = "model"

for word in word_list:
    for i in zip(word, search):
        print(i)

    if i[0] != i[1]:
        possible_words.remove(word)
        break

print(possible_words)

possible_word copies the values of word list, when i loop through to check if the word is not the same as the guess it should remove it from possible words. But when I print possible words it is every second word from word list.
