Question

what is archaic words and modern equivalents and what is difference between them​

Answer 1

Archaic words

These words are no longer in everyday use or have lost a particular meaning in current usage but are sometimes used to impart an old-fashioned flavour to historical novels, for example, or in standard conversation or writing just for a humorous effect. Some, such as bedlam, reveal the origin of their current meaning, while others reveal the origin of a different modern word, as with gentle, the sense of which is preserved in gentleman. Some, such as learn and let, now mean the opposite of their former use.
