Q: Question: I am trying to find a single word antonym for "exceed". I am using the word as a verb (so "beneath" doesn't work) and it should have a positive connotation (as in a golf score which falls below par). I thought of "subceed", which I like, and found a few Google hits but it doesn't show up in any reputable dictionaries. I've reviewed answers to similar questions and found no suitable alternatives. For example, the selected answer to What would be an appropriate opposite of "exceed"? suggested: "eluded" has a mostly negative connotation and implies intention "beneath" is not a verb "are below"/"did not meet" phrases I'm looking to replace "exceeded" in the following quotes with a single word (meaning something like "went below", "were under", etc.): "He never gets tickets because he always exceeds the speed limit." "To win the match, Tiger Woods must exceeded 4 strokes on the twelth hole." "To prevent freezing, do not exceed -20 degrees centigrade." 
Answer: I'd go for: You underrun the speed limit.

A: yes

Q: Question: I'm trying to describe a situation in which a person prepares for an event, then realises the event won't happen, and so they undo their preparations, returning to a state of unpreparedness. Whenever I search for the opposite of "prepare", I get words that describe a failure to prepare in the first place, or at best words that describe what happens to the preparations, not words that describe what happens to the person. Is there a word that captures what happens to the person as they return to a state of unpreparedness? 
Answer: There were several answers way, way off-base. Disengage was not bad but does not carry the same implications. Pigeonhole, defer, put off, undo also work. Undo everything is two words. Undo would do. (grin).

A:
no
