Silent eccentric permits entry (4,2)

I believe the answer is:

lets in

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

'permits entry' is the definition.
'lets in' can be an answer for 'permits' (letting in is a kind of permiting). I'm not sure about the 'entry' bit.

'silent eccentric' is the wordplay.
'eccentric' is an anagram indicator.
'silent' anagrammed gives 'LETS IN'.

Can you help me to learn more?
