IPA: /kənˈtɪɡ.ju.əs/
KK: /kənˈtɪg.ju.əs/
Connected or touching without any gaps; neighboring or adjacent.
The two countries share a contiguous border that allows for easy travel between them.
Contiguous → It is formed from "con-" (meaning together) and "tangere" (meaning to touch). The word describes things that are touching or sharing a common boundary, hence they are together in contact.
Think of things that are 'touching' ('tangere') each other 'together' ('con-') — that's why contiguous means they are in contact.
