Spatially is the adverb from spatial, and spatial is about space — not outer space, but the plain meaning of space: where things are, how big they are, what shape they are, how far apart they sit, how they are arranged. So when you say something happens spatially, you are saying: I am now talking about the position/size/shape/arrangement side of it. It answers 'where and how arranged?', not 'when?' and not 'how much?' You meet it most often as a contrast word. People say 'spatially, the two buildings are close, but they feel far apart' — near in position, not near in feeling. Or 'the data is spatially organised' — the information is arranged by place, like on a map. In tests and psychology books you hear 'spatially aware' or 'spatial reasoning': being good at picturing how shapes turn, fit, and stack in your head. It is a formal, written word. Geographers, architects, designers, scientists, and researchers use it a lot. In everyday talk almost nobody says it — a friend would just say 'in terms of where things are' or point and say 'here, next to this'. So it is a word you will read far more often than you will say. It is also often paired with another adverb to mark a difference: 'spatially and temporally' means 'in place and in time', a very common pair in academic writing.
