What can happen to inscriptions over time, making them challenging to interpret?

Inscriptions may be damaged or letters can be missing

It is evident that epigraphy has its limitations in revealing historical information. One significant constraint lies in technical factors, such as faintly engraved letters that lead to uncertain reconstructions. Moreover, inscriptions can suffer damage over time, resulting in missing letters or sections. Additionally, determining the precise meaning of words used in inscriptions can be challenging, especially when they are specific to particular places or time periods.
