I’ve often wondered about words like these, but Susie Dent explains:
You can be gruntled (satisfied), kempt (combed), couth (polite), ruthful (full of compassion), whelmed (capsized), and gorm-like (have an intelligent look about you). And, for a while in the 1600s, you could be shevelled too.
A commenter adds the words “chalant” and “consolate”, which were apparently first used in a New Yorker piece.
Also in that piece: “wieldy”, “descript”, “gainly”, “cognito”, “make bones about it”, “beknownst”, “it would be skin off my nose”, “both hide and hair”, “toward and heard-of behaviour”, “maculate”, “peccable”, “new hat”, “terminable”, “promptu”, “petuous”, “nomer”, “choate, “defatigable”, “committal”, and quite a few that I surely missed.
Immaculate and impeccable are odd ones. Does im at the front mean not? It’s not clear. Pressive? Pact? Mitate? Agination? Immiserate sounds the same as miserate. This can get very intricate. Although, you may think it to be not very tricate. Also, I hope you are being ritated rather than the more common negative of that.
“Indefatigable” could be shortened twice. Defatigable. Fatigable. Which means something very similar to indefatigable.
Timidate. Timate. Genious. Sipid. Cest. Ert and Ept, I’ve heard before. Nuendo. Finitesimal. Juriours,
For “over”, you could just put “der”.
I hope this posting has interested you. My apologies if, instead, you have been terested.
