tenero: as a writer of love-poetry; cf. Ovid (with whom it is a favorite word) Ov. Ars Am. 3.333 “teneri carmen Properti” ; Ov. Rem. Am. 757 “teneros ne tange poetas” ; Mart. 4.14.13 “tener Catullus” ; Mart. 7.14.3 “teneri amica Catulli.”
 Comi: in the year 59 B.C., in accordance with the Vatinian law, Julius Caesar settled 5O0O colonists at Comum, a town already established under Cn. Pompeius Strabo, and called the place Novum Comum. Como, the modern town, lies at the southern end of the westem arm of Lacus Larius (Lago di Como), about thirty miles north of Mediolanum (Milan).
 cogitationes: Catullus desires to entice his friend to visit him, and so speaks with playful vagueness of certain weighty matters that can be communicated only by word of mouth. The whole tone of the poem is opposed to any serious interpretation of the phrase.
 amici sui meique: the same playful mysteriousness of expression is kept up here, but Caecilius undoubtedly interpreted it correctly to mean that the friend was the writer himself. So Catullus speaks of himself to Alfenus in Catul. 30.2 as tui amiculi.
 quo tempore: denoting the starting-point of a continued action, as indicated by v. 14 ex eo; cf. Catul. 68.15 “tempore quo” with Catul. 68.20, where the continuance of activity from the initial period is clearly indicated.
 legit: sc. illa; she read the opening verses lent her by the author; cf. Catul. 42.1ff., where Catullus was unable to recover his tablets lent, perhaps, under similar circumstances. The custom of public recitation by the author himself was introduced later by Asinius Pollio (cf. Catul. 12.6).
 doctior: an epithet commonly applied to poets, especially of this school, which disdained the rude simplicity of its predecessors, and sought inspiration among the polished Alexandrians (Catullus is styled doctus by Ovid in Ov. Am. 3.9.62, by Lygdamus in Tib. 3.6.41, and by Martial in Mart. 7.99.7 and Mart. 14.152.1); Catullus means that a girl so appreciative of the best poetry must have within herself the attributes of a poet: so Propertius calls Cynthia docta (Prop. 3.13.11), and in Catullus Catul. 65.2 the Muses are doctae virgines.
 incohata: there is no reason to suppose, as some have done, any playful implication that Caecilius had been unwarrantably long in getting beyond the beginning of his work.
