Out of date dictionary’s?

Out of date dictionary’s?

In my story I am using a combination of modern and antiquated words that do not appear in the dictionary pre-installed Apple OSX10.9. I am finding more and more that these words do exist in paper copies of dictionary’s meaning that I have to spent time away from reading and editing to go and check the existence of these words.

Come on Apple get your finger out and fix the PROPER BRITISH ENGLISH dictionary and not the out of date American crap that seams to be installed!

Customised Spell checker and Auto-complete in OSX

Customised Spell checker and Auto-complete in OSX

I don’t know if this is at all possible but it is getting to a stage where a need a highly customised by lingual OSX dictionary, Spell checker, auto correct and Thesaurus all in one tool!

My problem is that with words like there, their and they’re I always end up picking the wrong one! I find that I can not get to grips with words that have multiple spellings but sound the same or words that are spelled differently to how I pronounce them 

I.E = The word sure – I have always pronounced it Shure  (Note the “H”) 

It is these kind of words that send me screaming and drive me up the wall.

Another problem I have is with through, thought and throat. again to most these words are miles apart in sound and meaning but again I cant grasp the difference when it comes to writing them down!

What I need is a plug-in that can pick up on these words and pop up a suggestion box with there meanings but works OS wide and not on individual programs. I am not a programmer and have no understanding how the Dictionary/Spell checker/Auto correct services work.

I hope someone out there can understand what I am wanting and point/help me build this.
