You have to understand that the append() method always appends a single item
to the list, be that a string or a list or whatever. If you want to append
words in a list to the list the logical approach is therefore to loop over
the words and invoke append for every word
for word in fword:
list1.append(word)
There is also a dedicated extend() method that takes a list (actually an
iterable) and appends all items in that list:
list1.extend(fword)
