You probably know the Hebrew word for Kosher - כָּשֵׁר (kah-SHEHR). Literally, the word means prepared.
The root כ.ש.ר (k.sh.r) is also used to imply that someone is naturally prepared for some task; that the person has talent or a knack for it. The word for talent or knack is כִּשָּׁרוֹן (kee-shah-ROHN).
To say that a person is talented, you'd say הוּא מוּכְשָׁר (hoo mookh-SHAHR) for a male and הִיא מוּכְשֶׁרֶת (hee mookh-SHEH-ret) for a female.
