before

The English preposition 'before' is a compound word that reveals one of the deepest metaphors in human language: the mapping of spatial position onto temporal sequence.‍​‌​‌​‌​‍​‌​‍​‌​‌​‍​‍​‍​‍​‌​‌​‌​‍​‌​‌​‍​‌​‌​‍​‍​‌​‍​‌​‍​‌​‌​‍​‍ To say something happened 'before' an event is to say it was 'in front of' that event — a spatial image applied to time. This metaphor is not unique to English; it is one of the most widespread conceptual mappings found in the world's languages.

The word descends from Old English 'beforan,' a compound of 'be-' (by, near, about — the same unstressed prefix found in 'behind,' 'below,' 'beside,' and 'between') and 'foran' (before, in front of, in the presence of). The element 'foran' is itself derived from 'fore' (in front), from Proto-Germanic *fura, which traces to the PIE root *per- (forward, through, in front of). This PIE root was extraordinarily productive: it also produced Latin 'pro' (for, in front of), Greek 'pró' (before), Sanskrit 'purá' (before, formerly), and the English words 'for,' 'fore,' 'forth,' 'first,' 'former,' 'far,' and 'from.'

In Old English, 'beforan' had three main clusters of meaning. The spatial sense ('in front of') was primary: 'he stood beforan the king' meant 'he stood in front of the king' or 'in the presence of the king.' The temporal sense ('earlier than') was already well established: 'beforan Cristesmæssan' meant 'before Christmas.' And a preferential sense ('rather than') also existed: 'I would choose death beforan dishonor.' All three senses survive in modern English.

The spatial-to-temporal mapping that 'before' encodes is based on what linguists call the 'ego-moving' or 'time-moving' metaphor. In one version, the speaker moves forward through time, so events 'in front of' the speaker are events not yet reached — future events. In the other version, time flows past the speaker like a river, so events 'in front of' (i.e., already visible, already passed) are past events. English 'before' uses the second metaphor: the past is 'before' us because we can see it, as one sees what is in front of one's face.

This is not universal. The Aymara language of South America explicitly places the past in front (the word 'nayra' means both 'eye/front' and 'past') and the future behind ('qhipa' means both 'back/behind' and 'future'). The logic is the same as English 'before': what you have already experienced is visible and therefore in front of you, while the future is invisible and therefore behind you. But many European languages have partially overridden this with the competing 'ego-moving' metaphor, where 'ahead' means 'in the future.'

The word 'before' participates in several important English constructions. 'Beforehand' (earlier, in advance) adds 'hand' in an old sense meaning 'position' or 'state.' 'Aforementioned' and 'aforesaid' use the related prefix 'afore-,' now archaic except in legal and formal registers. The nautical term 'before the mast' described the area of a ship where common sailors lived (the forecastle was before the main mast), and 'sailing before the wind' means sailing with the wind behind you, pushing you forward — a use where 'before' retains its purely spatial meaning of 'in front of.'

The family of words built on Proto-Germanic *fura and PIE *per- is one of the largest in English. 'First' comes from a Proto-Germanic superlative *furistaz (most forward). 'Former' comes from an Old English comparative 'forma' (earlier). 'Foremost' combines 'fore' with '-most.' 'Forth' (forward) and 'further' (more forward) extend the spatial sense. 'Far' comes from a related Proto-Germanic form. Even 'from' derives from the same PIE root, via the sense of 'forward from a starting point.' Together, these words form a web of spatial and temporal reference that pervades every register of English.

Phonologically, Old English 'beforan' /beˈfo.rɑn/ underwent the typical Middle English reduction of unstressed syllables, losing the final '-an' and weakening the first syllable to a schwa-like vowel: /bɪˈfɔːr/. The Great Vowel Shift had little effect on the stressed vowel, which was already an open-mid /ɔː/. The modern pronunciation /bɪˈfɔːɹ/ is thus close to what a late Middle English speaker would have produced.
