What other single words can you make using all of the letters in: INTERPOLATE?

I’m assuming you mean 3+ letters.

Pore, rope, late, teal, tea, eat, ate, pale, plate, tape, tap, pat, lop, lope, pole, pot, top, rot, tor, tore, tare, tear, ear, pear, part, art, pint, pit, tip, tit, trite, lite, per, rep, trip, trial, lier, liar, lie, tie, port, intro, into, treat…I can keep going….

Wordsmith’s anagram server finds none.

None

And I know I took the easy way out.

My bad, I’m thinking boggle-style.

No words, but one sentence: Let Porn Eat I. And a thing: Inert Ale Pot I need to go back to work and let these poor people fluther in peace

911

words with 3 or more letters. But this uses some letters twice like; trill, tripartite, and triplet. But this does not seem to be disallowed.
