English distinguishes between surfaces and containers; Spanish often uses one word for both.
dans, sur, à
French 'à' is used for cities, whereas English uses 'in' for cities.
in, auf, an
German prepositions change the noun's case (Dative/Accusative), which English does not do.
ni (に), de (で)
Japanese doesn't distinguish between 'in', 'on', and 'at' using these particles alone; it uses extra words like 'ue' (top) or 'naka' (inside).
fi (في), 'ala (على)
Arabic often uses 'fi' for 'at' as well, leading to 'in'/'at' confusion.
zai (在)
English prepositions come before the noun; Chinese uses a 'sandwich' structure.
