Current dictionary

I don’t know if others are having the same issue, I use English (UK) as the spellchecker language.
For the last year or so I have noticed that the current dictionary has many words missing and I spend too much time having to add simple words. Today is was :Tenerife" and it showed as an error and I had to dd it.
The thing is that the dictionary must have been changed a year or two back and probably with some update or upgrade.
My question then - Can we have the old dictionary back?
