About This Root
Fight is one of the bluntest, oldest words in English. It comes from Old English feohtan, 'to fight, contend, strive,' a core word of West Germanic stock (German still says fechten, 'to fence'). Unlike the many Latin roots English borrowed for 'conflict' — bell- (belligerent), pugn- (pugnacious), milit- (militant) — fight never went to school. It stayed a plain Anglo-Saxon word for a plain, physical thing: two people, fists or weapons, struggle.
Because it is a native Germanic word, fight builds its family the Germanic way — not with Latin prefixes, but by being glued onto other plain English words to make compounds. The simplest derivative is fighter, 'one who fights' (and, in the 20th century, a fast warplane built to fight other planes). Stick a noun in front of it and you name what is being fought: a firefighter fights fires, a prizefighter fights for prize money, and an effort can be crime-fighting when it fights crime. The pattern is dead simple — [thing] + fight = struggle against that thing.
Fight also stretched from the literal to the figurative without changing shape. You can fight a person, but you can also fight a cold, fight for your rights, fight back tears, or fight an uphill battle. The core never moves: there is resistance, and you push against it with effort. The verb is irregular — fight, fought, fought — a tell-tale sign of its ancient Germanic roots, since the oldest English verbs change their vowel instead of just adding -ed.
The takeaway: fight carries no Latin politeness. Every fight word is about confronting something head-on — with fists, with fire hoses, or with sheer determination.
Fight is so plain it explains itself: two fists, head-on. To build a word, just put what you're fighting in front of it — fire+fighter, prize+fighter, crime+fighting. And remember it's irregular: fight → fought → fought.

The few words from this family worth telling in full — one by one.
The irregular verb that anchors the family: fight → fought → fought. Beyond literal combat, it stretches into idioms English speakers use constantly — fight for a cause, fight back, fight off an illness, fight an uphill battle. The thread is always 'resist with effort,' whether against a person, a feeling, or a disease.
Two very different senses share one form. The human sense ('a fighter never gives up') praises grit and resilience. The military sense — a fighter jet — names a fast plane built to shoot down other planes. Same root, two worlds: the determined person and the combat aircraft.
A clean example of the [thing]+fighter pattern, and of how English modernizes. It replaced the older, gendered 'fireman' precisely because the compound is so transparent — anyone can read it as 'one who fights fire.' The same logic builds crime-fighting and prizefighter.
