躊躇（上宙留反下筯廬反考聲云躊躇不行也古今正字躊躇言猶豫也二字竝從足壽著皆聲）。

Hesitating (躊躇: the upper character has the fanqie zh[òu] + [l]iú; the lower character has the fanqie zh[ù] + [l]ú; the Kaosheng says: '躊躇 means not advancing.' The Gujin zhengzi says: '躊躇 means being undecided; both characters take zú as radical, with shòu and zhù as phonetics').
