I don’t think that giving similar-meaning words similar labels is a good idea. In one class, I had to struggle to distinguish between:
hypoeutectoid (“less than well-melting-ish”, such as steel with 0.022%-0.76% carbon)
hypereutectoid (“more than well-melting-ish”, such as steel with 0.76%-2.14% carbon)
hypoeutectic (“less than well-melting”, such as cast iron with 2.14%-4.30% carbon)
hypereutectic (“more than well-melting”, such as cast iron with >4.30% carbon)
(see https://en.wikipedia.org/wiki/Eutectic_system#Eutectoid for more details)
Although hypo- and hyper- don’t conform to your system (they have opposite meanings but similar sounds), -oid and -ic do, and it causes confusion and misunderstanding.
Re: dehumidifiers
A standalone dehumidifier will heat the air more than sweating can cool it. You can see that from conservation of energy and thermodynamics: evaporating water (eg. when you sweat) absorbs heat , and condensing water (eg. in a dehumidifier) releases an equal amount. You also need to pay a bit of extra energy to run the machine and to overcome entropy.
Using an air conditioner to dehumidify doesn’t have that same problem, as it vents the heat outside.
