noun
calligrapher; skilled penman
Refers to a person skilled in calligraphy or beautiful handwriting, often as an art form. The second gloss 'individual with good penmanship' is a broader, less formal extension.

She is a famous calligrapher and holds exhibitions.
祖父は書家ではないが、とても字がきれいだ。
My grandfather is not a calligrapher, but his handwriting is very beautiful.
Compound of 書 (writing, calligraphy) and 家 (person, specialist). The exact historical derivation is uncertain, but the word follows a common pattern for naming practitioners of an art.
