Skill

A skill or technique is a learned ability to do something. It could be playing a musical instrument or playing a kind of sport or even doing something simple like using a corkscrew. Someone who is trying to do something but not succeeding may be using the wrong technique. Skill does not always have to be something physical: it may refer to the way a person approaches a problem.

Examples of skills are:

Being able to handle a bow or a gun
Being able to speak a language
Reading and writing
Knowing how to use a computer program
