Can you work out the twelve words? Pay no attention to the colours of the grid, or to uppercase/lowercase letters!

Yorkshire, Jefferson and Wisconsin leap out, as does education.

From there I set the computer running with

DIM pc$(36)
OPEN "triplets.txt" FOR INPUT AS #1

FOR i = 1 TO 36
 LINE INPUT #1, pc$(i)
 pc$(i) = LTRIM$(RTRIM$(LCASE$(pc$(i))))
 PRINT pc$(i); " ";
NEXT
CLOSE

OPEN "\words\words9.txt" FOR BINARY AS #1
w$ = SPACE$(9)
DO
  GET #1, , w$
  IF EOF(1) THEN EXIT DO
  p$ = LEFT$(w$, 3)
  GOSUB check
  IF good THEN
    p$ = RIGHT$(w$, 3)
    GOSUB check
    IF good THEN
      p$ = MID$(w$, 4, 3)
      GOSUB check
      IF good THEN PRINT w$
    END IF
  END IF
LOOP
END

check:
  good = 0
  FOR i = 1 TO 36
    IF p$ = pc$(i) THEN good = 1: EXIT FOR
  NEXT
RETURN

which found

education
insolence
maelstrom
offspring
personnel
pimpernel
sovereign
springing
thirtieth
turquoise

but springing is out as it uses two ing's. Also, personnel and pimpernel cannot both be right as they both use nel and per. But it's personnel that would reuse the son from Jefferson, so pimpernel it is.

That gives us

Jefferson
Yorkshire
Wisconsin
education
insolence
maelstrom
offspring
pimpernel
sovereign
thirtieth
turquoise

That's only 11.  Looking at D's answer, it looks like kilometre is the 12th, and not in my word list, due to its spelling.
