Scottish Gaelic spellchecker (Universal) автор Akerbeltz, Kevin Scannell

This will add a Scots Gaelic spellchecking addon. It will spellcheck just over 2.8 million words, making it by far the biggest Gaelic spellchecker to date.
Please note the following:

► This is a universal spellchecker. That means it will accept any spelling that is correct in both traditional systems and GOC. For example, it will accept mór and mòr, doras and dorus and dàinig and tàinig.

Once you've installed it, go to:

► Innealan/Tools
► Roghainnean/Options
► Roghainnean adhartach/Advanced Options
► Put a tick against Ceartachadh-litreachaidh beò/Check Spelling As You Type

This will then underline words you type that the spellchecker thinks are wrong. Right click to see the suggestion
