To test or experiment with something to see how it works or whether it's suitable.
This phrase combines 'try' meaning to attempt or test, with 'out' suggesting thoroughness or completion. The construction became standard in English by the 18th century, often used in contexts of testing new methods or products.
The genius of this phrase is in the 'out' - it suggests not just a quick attempt, but a proper trial run. It's the difference between touching something and actually using it long enough to form a real opinion.
