former

The word 'former' is a comparative adjective built on the same root as 'first,' and understanding their relationship illuminates how English constructs its vocabulary of priority and sequence.‍​‌​‌​‌​‌​‍​‌​‌​‍​‍​‌​‌​‌​‍​‍​‍​‌​‌​‌​‌​‍​‌​‍​‌​‌​‌​‍​‌​‍​‍​‌​‍ While 'first' is the superlative ('most before'), 'former' is the comparative ('more before') — though both derive from the PIE root *per- meaning 'forward' or 'before.'

Old English 'forma' meant 'first' or 'foremost.' It descended from Proto-Germanic *furma-, itself from PIE *per-. In Old English, 'forma' functioned as a positive adjective (not yet a comparative), and it was used interchangeably with 'fyrst.' During the Middle English period, the comparative suffix '-er' was added to create 'former,' explicitly marking the word as a comparative form: the former of two things is the one that came more before.

This comparative structure mirrors the 'latter' in the common English pairing 'the former and the latter.' 'Latter' is similarly a comparative, built on 'late' with the comparative suffix '-er': the latter of two things is the one that came more late. The pairing is thus perfectly symmetrical — two comparatives, one of priority and one of recency, used together to distinguish the first and second of two items mentioned.

The distinction between 'former' and 'first' is partly one of scope. 'First' can operate in a sequence of any length: the first of three, the first of a thousand. 'Former' is typically restricted to a choice between two: 'the former option' implies exactly two options under consideration. This restriction reflects the comparative morphology — comparatives in English inherently involve a binary comparison.

The Old English root 'forma' also gave rise to the now-archaic 'formost,' which was later reshaped by folk etymology into 'foremost' (as if it were 'fore' + '-most,' a double superlative). In fact, 'foremost' contains a historical superlative suffix '-ma' (in 'forma') plus the additional superlative '-ost,' making it etymologically a triple comparison: 'fore' (before) + superlative + superlative. English is not alone in this kind of morphological excess — Latin 'primus' (first) was itself sometimes given a comparative form 'prior' (earlier), which English also borrowed.

The adverb 'formerly' (in the past, at an earlier time) derives straightforwardly from 'former' with the adverbial suffix '-ly.' It entered regular use in the sixteenth century and quickly became the standard way to indicate that something was once the case but is no longer: 'the city formerly known as Byzantium.'

The word 'former' also acquired a specific institutional usage in British English, particularly in education. A 'former' of a school (as in 'sixth-former') refers to a student in a particular 'form' or year group — but this 'form' derives from a different etymological source (Latin 'forma,' meaning 'shape' or 'pattern'), not from the 'fore/before' root of 'former.'

In contemporary usage, 'former' appears most frequently as a title modifier: 'former president,' 'former champion,' 'former spouse.' This usage carries an interesting emotional weight — it simultaneously acknowledges a past status and marks its conclusion. Calling someone a 'former' anything is inherently retrospective, tinged with the passage of time.

The PIE root *per- that underlies 'former' is one of the most prolific in the language. Through Germanic, it gave 'for,' 'fore,' 'before,' 'first,' 'far,' 'forth,' 'further,' and 'former' itself. Through Latin, it produced 'pre-,' 'pro-,' 'prior,' 'prime,' 'prince,' 'premier,' and dozens more. Through Greek, it yielded 'proto-,' 'pro-,' and 'para-.' The word 'former' is thus embedded in an enormous network of English words all expressing variations on the theme of being ahead, in front, or before.
