re [n] thinks about unfortunate things that might happen - "What kind of ditionary gives a verb definition to a noun?"

[One] assumes "[One who] thinks about unfortunate things that might happen" is implied.

[One] assumes that this is a regular practice employed by this dictionary for some reason.

BTW it is interesting that there is a word for people who are fussy about "pots", namely, "fusspots".

It seems only fair that there should be a word for someone who is fussy about other kitchen utensils, such as knives.

How about telling your mother-in-law you are a "fusscutter" or a "fusscutup", Father Steve?
