Dictionaries
- Stòr-Dàta Briathrachais Gàidhlig - The dictionary of Sàbhal Mòr Ostaig. The search interface also ties in with a list of other online dictionaries. As with most online-dictionaries, you get a big list of words without explanations, so finding the right one can be a bit difficult sometimes. It will do for starters though, and I use it all the time. It's also very convenient for finding words fast that you have forgotten, or if you wish to read a text and don't want to spend ages trawling though a book for the words. It has the base forms of words listed, so if you run across an irregular form you don't know the base form for, you won't find it. Select Briathrachan Beag for that, it has some inflected forms listed. It's only a little dictionary though, as the name says (beag = little).
- Am Faclair Beag - A New Scottish Gaelic / English Bidirectional Dictionary incorporating Dwelly. The Faclair nan Gnàthasan-cainnte which to date was on the Akerbeltz site is being integrated into the Faclair Beag.
- Dwelly-d - The online version of Dwelly's great Scots-Gaelic/English dictionary
- Colin Mark's Dictionary @ Google Books - You can use Google Book's search function to search the dictionary in both directions. Not all pages are available for display, but if you own the dictionary you can use the page number to check in your copy when searching for English words.

Grammar
- akerbeltz.org - Two sections of this site will be interesting for you grammar-wise. Beagan Gràmair - A Bit of Grammar - Explains how the pronunciation works, and covers some important grammar points. Some of it is written in a humorous way, so it's actually quite fun to read. It uses the IPA for pronunciation, which might look a bit complicated in the beginning. Don't let it put you off, you only need to learn to recognize the symbols used for Gaelic, and not the whole alphabet. It's the only way to get an exact transcription of the sounds. Fuaimean na Gàidhlig - The Sounds of Gaelic - Here you can fill the IPA symbols with life and listen to MP3s.
- TAIC - This is not a grammar page per se, but an online course. Still, it is pretty gammar oriented, so you can use it as a grammar resource as well. If you have problems with their programming, here's a direct link to the lessons.
- Gaelic Tip of the Week - Cailean Mark's Gaelic tip of the week. He explains how to find the right expressions for what you want to say, so you won't be speaking Beurlig.

Online Courses
- Beag air Bheag - Little by Little - The BBC's online course, Flash and HTML versions available. Each lesson gives a few phrases, then a bit of explanation, and some sample conversations. You can listen to all of it.
- Colin and Cumberland - The BBC's learning game. It's good to practice some basic vocabulary in a fun way. I started in Colin's house in the hall, with Parts of the Body. For some of the games you should have a faster computer than I have though, but I guess that won't be too much of a challenge...
- TAIC - An online course that is a bit more grammar-oriented, and also provides sound. If you have problems with their programming, here's a direct link to the lessons.

Other Online Resources
- BBC Alba Tbh - If you're in the UK, you can watch Gaelic TV online. For those outside the UK, only selected programmes are available.
- BBC Learn Gaelic - There are more learning resources on the BBC site, e.g. An Litir Bheag for relative beginners and Litir do Luchd-Ionnsachaidh for advanced learners. You can download MP3 files and the corresponding text as PDF. At Aig Cridhe ar Ciùil, you can listen to Gaelic music; written lyrics are provided. I always found music a very convenient and fun way to practice my pronunciation, so give it a try.
- Radio nan Gaidheal - The BBC's Gaelic language radio station. Go to "Èist a-rithist" to listen. I suggest you do this a lot, even if you don't understand a word, just let it run in the background. It will help you get used to the patterns of the language, even if you don't pay any attention. Over time, you will learn a lot without having to expend any extra effort.
- How to learn Gaelic by TIm - Very valuable advice on learning strategies by Tim of Mill a h-Uile Rud.
