Help!

can anyone explain me what the difference between Primer and a liner is? I know it might be a stupid question, but somehow i cant find the answer online..
I know that the primer is a part of the adhesive(bonding) system which consist of Etchant, Primer and Adhesive. And then I know that a liner is used to protect the pulp before placing some restorative materials(amalgam and composite++), so is liner also a part of the adhesive system or is that just a protecting layer we are placing in the cavity before etching?
Thanks

The purpose of a liner is to protect the pulp. It does not help bond the filling to the tooth. It helps protect the tooth and hopefully prevent the need for root canal therapy.
