I WILL TALK TO YOU LIKE A DUTCH UNCLE, phr. (common).I will reprove you smartly. [The Dutch were renowned for the brutality of their discipline. Uncle is the Latin notion of patruus, an uncle, severe guardian, or stern castigator. Hence Horace, 3 Od. xii. 3, Metuentes patruæ verbera linguæ (dreading the castigations of an uncles tongue); and 2 Sat. iii. 88, Ne sis patruus mihi (Dont come the uncle over me). A DUTCH UNCLE = therefore, an uncle of peculiar fierceness.]
