Here is a step-by-step guide on how to accomplish this task in Python:

1. Open the file using the `open()` function. This function takes two parameters: the name of the file you want to open and the mode in which you want to open it. In this case, you want to open the file in read mode, so you would use `'r'` as the second parameter.

```python
file = open('romeo.txt', 'r')
```

2. Read the file line by line using a for loop. In Python, a file object is also an iterable object, which means you can use it in a for loop and it will return its lines one by one.

```python
for line in file:
```

3. Split each line into a list of words using the `split()` method. This method splits a string into a list where each word is a separate element in the list.

```python
words = line.split()
```

4. Check if each word is already in the list. If it's not, append it to the list. You can do this using an if statement and the `not in` operator.

```python
for word in words:
if word not in word_list:
word_list.append(word)
```

5. After the for loop, sort the list using the `sort()` method. This method sorts the elements of a list in a specific order - either ascending (by default) or descending.

```python
word_list.sort()
```

6. Finally, print the sorted list.

```python
print(word_list)
```

Here is the complete code:

```python
file = open('romeo.txt', 'r')
word_list = []

for line in file:
words = line.split()
for word in words:
if word not in word_list:
word_list.append(word)

word_list.sort()
print(word_list)
```

This code will open the file `romeo.txt`, read it line by line, split each line into a list of words, add each word to a list if it's not already in it, sort the list, and print it.
