It's inclined to be used in child's play (5)

Ross

I believe the answer is:

slide

I'm a little stuck... Click here to teach me more about this clue!

'used in child's play' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'it's inclined' is the wordplay.
I cannot quite see how this works, but
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found within the answer.
The remaining letters 'slid' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'to be' acts as a link.

Can you help me to learn more?

(Other definitions for slide that I've seen before include "Playground equipment with sloping surface" , "Microscope glass" , "Drop" , "Transparency" , "that's put under the microscope" .)
