I think "cap" can only be used for setting upper limits but not lower limits, any idea for the verb for setting lower limits?


The mortgage rate is capped at 3% for three years. <-> The upper limit of the mortgage rate is 3% for three years.

The lower limit of the mortgage rate is 1%. <-> The mortgage rate is [what is the verb?] at 1%.

  • What exactly do you mean with lower limits? Do you mean minimums?

  • You should write an example using the words in the context you intend.

  • I always see the word "cap" used for setting upper limits but, in my opinion, it can be used for setting lower limits too.

The cap for the mortgage is 3% and the bottom is 1%.

This counterpart can't be verbed though.

The mortgage is capped at 3% and bottomed at 1%.

You must use limited at the bottom to or something similar.

  • While I don't doubt the technical accuracy of your answer, I don't think that this usage would be well/widely understood. But that could just be me. Apr 23, 2019 at 16:36

Capped at X means "can't go higher than X", which implies X will be subject to increasing in quantity.

Loss can be capped (it means the amount of loss can't be any higher than X), but if something is decreasing in quantity, or not changing in quantity, capped at X doesn't work too well.

If the quantity change is variable or negative instead of mostly increasing, cap might not be the best word, you probably want to simply say "limited" or use "ceiling" and "floor" to describe the upper and lower limit, respectively.

    Generally, you hear "floor" as the lower limit of something. For example, "the NHL salary cap is set at $80 million and the salary floor is $70 million." Use of ceiling isn't quite as universal.
