Does it worth to register?

[DNBro]

Does it worth to register a keyword having some Google advertisement coming on singular keyword, singular one is already registered, but plural is not registered yet.

Like an example only

Cheap domain registration: registered.
Cheap domain registrations: unregistered.

Is it worth to register such keywords irrespective of keywords?

Please share your views.

Thanks
