How do I say?

How do I say? is where thou puts any askings as to how something ought to be said (I dare say thou could already tell that). Put a new heading for each asking, with the word(s) as the heading 's name, and below write anent the word(s) to give a better clue as to what is needed. Also write any thoughts thyself has on the word.

Tolerance level
As in 'the load was above the tolerance level of the framework'. I would like the word to fit with all meanings, not only the narrow meaning of 'load'. I think the word ought to be built upon 'brook', but the only thought I can come up with is 'brookwidth'. Oswax Scolere
