OK - a puzzle that Stitchman used to enjoy making. Below are 45 words that can be arranged into fifteen logical groups. Trouble is, several of the words can fit into more than one group, but there is only one set of groups that will use up all the words. (He was a devious old *&%£!, was Stitchman).

See if you can figure out a couple of the groups along with the reason they are grouped together.

ACCORD, AMITY, APOLLO, BINKY, CAPRICORN, CARAT, CHEMISTRY, CONCORD, CROWN, DOMINION, EARTH, ESCORT, GEMINI, GOLD, GRAIN, INERT, JAGUAR, JUPITER, KRYPTON, LEAD, LEO, MARS, MERCURY, MINERVA, MUSTANG, NEWTON, NOBLE, OUNCE, PEACE, PHYSICS, POUND, POWER, PRESSURISED, PROBE, SATURN, SHADOWFAX, SILVER, TAURUS, TIME, THRONE, TIGER, VENUS, VIRTUE, WORK, YEN

I'll take the first stab...mustang, Shadowfax, and Silver are all horses?

This is what delighted the Needler so much!

Nice try, L4L - the category's fine, but two out of three for the rest!

Taurus,Capricon,Gemini,Leo,=Zodiac

They're groups of three, Haroula - which three out of the four are you going for?

Jaguar, Mercury, and Saturn. All are/were car manufacturers.

carat, grain, ounce? - units of measurement

Apollo, Mercury, Gemini are all space programs.

Taurus,Capricon,Leo

Nobel Prize Categories: chemistry, peace, physics

BabaLa, Haroula, Jema - all good!

Sondi - two out of three.

Coreoverload - I have a category similar to yours, but it doesn't contain any of your answers

Earth Jupiter and Venus - all planets

Two out of three, Gerry!

How about Earth Jupiter and Mars? (Planets)

Oh, how well I remember these. "Stitchie" loved to torture us with them. I miss him. Thanks for bringing them back, Oh son of Needler.

I'll try...
Binky, Shadowfax, Silver, fictional horses
