Relevant

Like the even ghastlier applicable, an adjective that carries precisely no semantic content. For, if a concept is not relevant, it goes without saying that it is not — well, relevant to the subject at hand. So one hardly needs to add a qualifier to distinguish the things you are not talking about from ones that you are.

Which inevitably calls to mind that wonderful scene from the young ones:

In The Young Ones, just before The Damned kicked off a boisterous rendition of their punk classic Nasty, Mike and Vyvyan agonised over their failure to get their new video recorder working. It is a parable for today’s uncertain times.

Mike: Maybe you shouldn’t have poured all of that washing-up liquid into it.

Vyvyan: It says here, “ensure machine is clean and free from dust”.

Mike: Yeah, but it don’t say “ensure machine is full of washing-up liquid”.

Vyvyan: Well, it doesn’t say “ensure machine isn’t full of washing-up liquid”.

Mike: Well, it wouldn’t would it? I mean, it doesn’t say “ensure you don’t chop up your video machine with an axe, put all the bits in a plastic bag and bung them down the lavatory.”

Vyvyan: Doesn’t it? Well maybe that’s where we’re going wrong.
