Palimpsest

Palimpsest:

Originally the term for a parchment on which several inscriptions had been made after earlier ones had been erased. The characteristic of the palimpsest is that, despite such erasures, there are always traces of previous inscriptions that have been 'overwritten.' Hence the term has become particularly valuable for suggesting the ways in which the traces of earlier 'inscriptions' remain as a continual feature of the 'text' of culture, giving it its particular density and character. Any cultural experience is itself an accretion of many layers, and the term is valuable because it illustrates the ways in which pre-colonial culture as well as the experience of colonization are continuing aspects of a post-colonial society's developing cultural identity.

Questions:
1. Does it make sense?
2. Is it useful? (Is there a simpler word you would use to describe this?)
3. Think of examples?
