It's on tape and can also be seen at Monte (5)
I believe the answer is:
video
'be seen at monte' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'it's on tape and can' is the wordplay.
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'on' says to put letters next to each other.
'tape' becomes 'vid' (short for videotape).
'and' means one lot of letters go next to another.
'can' becomes 'o' (I can't justify this - if you can you should believe this answer much more).
'e' put after 'vid' is 'vide'.
'vide'+'o'='VIDEO'
'also' is the link.
Can you help me to learn more?
(Other definitions for video that I've seen before include "Transmitter of televised image" , "Recorded visual image" , "Who killed the radio star? (5)" , "Capture on film" , "Recording medium" .)
