Words such as lass, lad, sassenach, laird and their derivatives are characterized by the highest frequency of occurence. They are used in colloquial speech, mostly in a conversion or a dialogue. These words, especially lass and lad, have survived to the present day and may be a key to understanding the culture of Scotland.
It is necessary to pay attention to the word sassenach as well, since it is a culture-specific element that does not have an equivalent in the English language. This noun is used in relation to the Saxons in a disdainful manner. This word is frequently used in the novel due to the fact that this is how the Scots appeal to the main character who is of British origin.
