[fudgee logic]

Is this the correct understanding for naming conventions of plugs and
adapters:

(1) A lead which has a phono plug at each end can be referred to as
"phono plug to phono plug" lead. That much is ok.


(2) But is an adaptor (or coupler) which has a phono socket at each end
referred to as "phono socket to phono socket" adaptor (or coupler)?

Here's one: http://www.rawpower.co.uk/acatalog/sky_761.260.jpg

Would not also be likely that this could be referred to by its ability to
join two phono plugs and therefore gets called "phono plug to phono plug"
adaptor (or coupler)?
