across from
Synonym discussion
Sense: preposition/1
Across from, opposite, and facing all describe a position on the other side of something. 'Across from' is the most neutral and common option in everyday spoken English — it works for streets, rooms, tables, and any other physical gap. 'Opposite' is slightly more formal and often appears in written directions or official descriptions ('the hotel opposite the station'). 'Facing' draws attention to orientation: two things looking at or pointing toward each other ('two buildings facing each other'). Use 'across from' as the default in conversation; use 'facing' when the idea of looking directly at something matters; save 'opposite' for more careful or formal writing.
Etymology
The phrase 'across from' combines the preposition 'across' (from Old French 'a croiz', meaning 'in the form of a cross') with 'from' (Old English 'fram', indicating separation or origin). Together they express the idea of being on the opposite side, separated by a space. The phrase became common in the 19th century as a clearer alternative to simple 'opposite', especially in American English.
