Exercise 19: Temporal clauses: ubi & postquam
In these sentences two things happen, one after another; the earlier action/event/state is marked by ubi/postquam, and the verb in the ubi/postquam clause is in the perfect (indicative).
NB postquam may appear as two words, post & quam, which may even be separated (and quite far apart). In this case gloss the post as ‘later’ and the quam as ‘than’. Alternatively, you could mentally transfer the ‘post’ to where the ‘quam’ is.
Thus ‘After Caesar killed the slave, he saw the queen.’ can be represented by any of the following three sentences:
ubi Caesar servum necavit, reginam videbat.
postquam Caesar servum necavit, reginam videbat.
post reginam videbat quam Caesar servum necavit.
