Etymology
Origin of precision
First recorded in 1630–40; from Latin praecīsiōn-, stem of praecīsiō “cutoff”; equivalent to precise + -ion
Explanation
Use the noun precision to describe something that's exact, such as the work of a carpenter who's made 100 identical pieces of railing for a grand staircase. Precision is similar to perfection in that both words suggest that something could not possibly be better. However, perfection describes something that's flawless, such as a beautiful sunset. Precision, on the other hand, is more about accuracy, like computing the exact second that the perfect sunset will occur.
