Considering the 'back' is used as an adverb meaning 'In, to, or toward a former condition' can I use it in these cases?
Susan was looking at Jack, then something made her look away, then she looked back at him.
I'm asking this because 'look back' is also a phrasal verb that is normally used to mean 'look backwards' or 'think about something in the past'. So in this case 'back' would simply mean 'again'.
The second example is very similar, only with the verb 'turn'.
Susan was looking at Jack, then something made her look away, then she turned back to him.
What I want to mean is that Susan resumed her attention towards him. But even in this case, 'turn back (to)' is also a phrasal verb that has other meanings. So, can I use the word 'back' in this literal sense without causing confusion to the reader?
A third example would be with the verb 'sit'. 'Sit back' is a phrasal verb with its own meaning, but can I use it to mean 'sit again'?
