What does fettle mean?
Fettle is a compact, characterful English word that works both as a verb and, in limited fashion, as a noun. As a verb, it means to put something into good order — to adjust, tidy, or repair it — and it is heard most often in Britain and northern England, typically applied to machines, tools, or handiwork that needs skilled tinkering rather than major overhaul. Related industrial uses survive in engineering and pottery, where 'fettling' describes trimming away rough edges and surplus material from a cast or fired piece. As a noun, a person's fettle is their condition or state of health, but this sense now lives almost entirely within the pleasing set phrase 'in fine fettle', meaning hale, spirited, and on top form. The word traces back to Old English, when a 'fetel' was a girdle or strap and the verb meant to gird oneself up — fittingly, since fettling still means getting ready for action. Warm, informal, and faintly old-fashioned, it adds charm wherever precision about readiness and condition is called for.
To put into a fit or proper state; to tidy, adjust, or repair, especially machinery or craftwork.
"The mechanic fettled the carburettor until the engine ran smoothly."
Informal; chiefly British and Northern English dialect.
A person's condition or state of fitness, used almost exclusively in the phrases 'in fine fettle' or 'in good fettle'.
"At ninety she was still in fine fettle."
Rarely used outside these fixed expressions.
Very rare; the plural is not established in common usage, and the noun normally appears only in the singular within set phrases like 'in fine fettle'.
The only place most people ever meet 'fettle' is inside one glowing phrase — 'in fine fettle' — but it began life as an ordinary word for belting yourself up before work.

Etymology of fettle
Fettle descends from Old English 'fetel', meaning a girdle or belt, and its earliest verbal sense was to gird or bind oneself up, hence to make ready. The word passed through Middle English and settled into regional British use, developing its modern meanings of putting things in order and repairing them. Its industrial senses arose later, giving engineering and pottery the term 'fettling' for finishing rough surfaces. It is not known to have widely used cognates in other modern languages.
