tour
Latinturn, go round (as on a lathe)
About This Root
The root tour starts in a workshop. Greek tornos was a lathe — and also a tool for drawing circles. Latin borrowed it as tornus and built the verb tornāre, "to turn on a lathe": to spin a piece of wood or metal round and round while a blade rounds it off. A lathe turns things smoothly, in a circle, and brings them back to where they started. Keep that picture in mind, because the whole family follows it.
The verb came into English very early. Old English took tornāre as turnian, and Old French torner later reinforced it, giving us turn — one of the busiest verbs in the language. Turn a wheel, turn a page, turn left, turn twenty, turn into a frog: every sense is some version of rotating or changing direction. Add re- (back) and you get return: to turn back the way you came, or to send something back where it belongs. English kept building with its own words too: overturn (turn over, capsize, reverse a decision), downturn (a turn downward in business), turnover (how fast stock or staff "turn over"; also total sales), turncoat (someone who turns their coat — switches sides) and turnpike (originally a spiked barrier that turned to let travellers through, later a toll road).
French took a second path. From tornus it made the noun tour, "a turn, a round, a circuit." In English a tour became a journey that goes round from place to place and comes back home — a loop, not a one-way trip. The late 18th century gave us the tourist, and tourism and touring followed. Other French words kept the turning image:
- de- (away) + tour → detour: a turn away from the direct road.
- con- (together, all around) + tour → contour: the line that goes all the way round a shape — its outline. Contour lines on a map circle the hills.
- en- (in) + tour (around) → entourage: the people who surround someone important.
- tournament: from Old French torneiement, a contest in which knights turned and wheeled their horses to charge again and again.
- tourniquet: a French word shaped by tourner, "to turn" — a band you turn tighter around a limb to stop bleeding.
The most surprising member is attorney. Old French atorner meant "to turn to, to assign": a- (to) + torner. An attorney was "one who has been turned to" a task — appointed to act for someone else. The spinning lathe is long gone; only the legal role remains.
Two warnings. First, tour is easily confused with tort (Latin torquēre, "to twist": distort, extort, torture). The two verbs are not related. Tort words twist something by force and bend it out of shape; tour words turn round smoothly and come back. Second, tornado looks as if it should belong here, but it comes from Spanish tronada, "thunderstorm"; only its spelling was later reshaped by tornar, "to turn," which is why it looks so convincing.
The pattern: wherever you see tour or turn, picture something going round — a wheel, a road that bends, a trip that loops back home.
Picture a lathe: a block of wood spins round and round and comes off smooth and rounded. That spin is tour. turn = spin it; return = turn back; a tour = a trip that loops round and comes home; a detour = turn off the straight road; a contour = the line that goes all the way round.

The few words from this family worth telling in full — one by one.
turnThe everyday giant of the family, in English since Old English (turnian, from Latin tornāre).
The everyday giant of the family, in English since Old English (turnian, from Latin tornāre). Nearly every sense is a version of rotating or changing direction: turn a key, turn left, turn the page. From 'change direction' it slid to 'change state': milk turns sour, leaves turn red, a person turns forty. As a noun it means a go in a sequence — 'it's your turn' is the circle coming round to you.
Open turnreturnre- (back) + turn = 'turn back.' The literal sense is going back the way you came (return home) or sending something back (return a book).
re- (back) + turn = 'turn back.' The literal sense is going back the way you came (return home) or sending something back (return a book). Business English adds a less obvious sense: a return on investment is the money that 'comes back' to you, and a tax return is the form you send back to the government. Every use keeps the round-trip shape: out, then back.

A band's world tour circles city after city before heading home; a guided tour takes you round a building and back to the entrance. From it came tourist (late 18th century), tourism and touring.

That is why a map's contour lines circle the hills — each one goes round the land at a single height — and why a contoured seat follows the curves of your body.

The most surprising member. From Old French atorné, past participle of atorner 'to turn to, assign' (a- 'to' + torner 'turn'). An attorney is literally 'one who has been turned to' a task — appointed to act on someone else's behalf. The lathe and the turning have faded completely, leaving only the legal sense; 'power of attorney' still means the authority to act for another person.

The classic look-alike. tort comes from torquēre 'to twist, wrench': distort, extort, torture, retort — force that bends something out of shape. tour comes from tornāre 'to turn on a lathe': turn, return, tour, detour, contour — smooth turning round and coming back. The two Latin verbs are unrelated. Test: wrenched out of shape → tort; going round → tour.
Both mean 'turn,' but vers (vertere) is about turning to face a new direction or turning into something else: convert, divert, invert. tour (tornāre) keeps the lathe's picture of going round in a circle: tour, contour, return. Test: turning toward or into something → vers; going round → tour.
rot (rota, 'wheel') names the turning thing itself: rotate, rotation, rotary. tour names the lathe's turning action and the round trip it suggests: turn, tour, return. A wheel spinning in place → rot; going round and coming back → tour.
