One watches them being projected (5)
I believe the answer is:
films
'one watches' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'them being projected' is the wordplay.
I cannot really see how this works, but
'being' could be 'ms' (Ms. is an example) and 'ms' is found within the answer.
The remaining letters 'fil' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for films that I've seen before include "pictures" , "Movies" .)
