Lexicon The majority of the vocabulary of Scottish Gaelic is of Celtic origin. However, Gaelic contains substantially more words of non-Goidelic extraction than Irish. The main sources of loanwords into Gaelic are the Germanic languages English, Scots and Norse. Other sources include Latin, French and the Brittonic languages. Many direct Latin loanwords in Scottish Gaelic were adopted during the Old and Middle Irish (600 AD-1200 AD) stages of the language and are often terms related to Christianity. Latin is also the source of the days of the week ("Monday"), (Tuesday), ("Saturday") and ("Sunday"). Brittonic The Brittonic languages Cumbric and Pictish were spoken in Scotland during the Early to High Middle Ages, and Scottish Gaelic has many Brittonic influences. Scottish Gaelic contains a number of apparently P-Celtic loanwords, but it is not always possible to disentangle P and Q Celtic words. However, some common words such as ("legacy"), (; "mountain") and (; "bush") are transparently Brittonic in origin. Scottish Gaelic contains a number of words, principally toponymic elements, that are more closely aligned in their usage and sense with their Brittonic cognates than their Irish.
