For something to be “technical”, it has to be quantifiable and have a “Unit Of Measure”.
Unit Of Measure
This can be, for example, miles, m.p.h, pounds, feet, yards, molecular weight, etc.
Words that are not technical
Lots, many, etc. These kind of words are basically useless. If you are not certain of an exact quantity, simply say that you are not sure of the quantity or measurement. A “couple” = 2, a “few” = 3, but these are not technical terms.
Money has an exact number associated with it, but is not a scientific concept, and therefore, not technical. There are underlying forces that vary the exact value (i.e. the Gold Standard, Inflation, exchange rate, etc.) A dollar in the United States won’t necessarily buy you the same thing in England.
