It seems like you're asking for a step-by-step guide on how to write a program that fulfills the given requirements. Here's a Python solution:

Step 1: Accept the input strings S1 and S2. S1 may contain spaces, and S2 is a single word.

```python
S1 = input().strip()
S2 = input().strip()
```

Step 2: Split the string S1 into a list of words.

```python
words = S1.split()
```

Step 3: Append the string S2 to the list of words.

```python
words.append(S2)
```

Step 4: Sort the list of words in lexicographical order.

```python
words.sort()
```

Step 5: Join the sorted list of words back into a string, with each word separated by a space.

```python
result = ' '.join(words)
```

Step 6: Print the resulting string.

```python
print(result)
```

When you put it all together, the complete program looks like this:

```python
S1 = input().strip()
S2 = input().strip()
words = S1.split()
words.append(S2)
words.sort()
result = ' '.join(words)
print(result)
```

This program will take two inputs, S1 and S2, and output a sorted string that includes all words from S1 and S2.
