Frontier and border are synonyms,but are used in different contexts.
Border is talking about a specific edge of the country or an area. Something that can be clearly marked. It’s usually an official property line that marks where one country/area begins and another ends.
The US border with Canada is huge.
Frontier is something more general. It is not a specific line, but an area. It is usually an area or a district near the boarder line.
Soldiers were guarding the frontier near France.
Frontier can also be used to mean a certain limit.
frontiers of knowledge, frontiers of mathematics, etc.
biraz araştırdım. aslında ikisi eş anlamlı fakat, bazen border belirli bir sınırdan bahsederken, frontier genel anlamda sınırı ifade edebiliyormuş.
burada,
"Ottoman-Safavid (safevi?) sınır bölgesi, ek olarak, ülkeleri ayıran bir sınır olduğu kadar, politik bir sınırdır."
