If we look back at the introduction, we can see words with ro–leasachain àicheil (negative prefixes).
Gaelic, like English, uses prefixes to change the meaning of words, such as making a word àicheil (negative).
In the opening passage, we saw examples of different prefixes: ana–, eu–, mì–, neo–and eas– which usually? cause the following word to lenite.
These generally have the same meaning as English negative prefixes: un–, im–, in–, il–, ir–, and dis–.
