Archaisms

Archaisms can either be used deliberately (to achieve a specific effect) or as part of a specific jargon (for example in law) or formula (for example in religious contexts). Many nursery rhymes contain archaisms. Some archaisms called fossil words remain in use within certain fixed expressions despite having faded away in all other contexts (for example, vim is not used in normal English outside the set phrasevim and vigor).
