something can be done to it

[kadioguy]

On BBC Learning English's session, it says:

-able
Creates an adjective meaning that the subject can do something OR that something can be done to it.

Example words: excitable, employable, pleasurable, enjoyable, loveable, readable, breakable, moveable
-----
What does 'something can be done to it' (especially 'to it') mean?

(Update)
Does 'it' mean 'an adjective' and 'to it' mean 'reaching a particular state'?

See definition 4 http://www.oxfordlearnersdictionaries.com/definition/english/to_1?q=to

PS - I also posted the same question here, but all of your answers are unique.

What does 'something can be done to it' (especially 'to it') mean?

For example,
Glass is breakable.
The subject is "glass". The word "breakable" is an adjective that says we can do something to "glass" (break it).

Thank you.

However, I would think it is:
...an adjective meaning that something can be done to it.

In this condition the antecedent of 'it' is only 'something' or 'an adjective'. :?:

Creates an adjective meaning that the subject can do something OR that something can be done to it.

In the above, "it" refers to " the subject", not to "an adjective".
