Let's turn regular. Cool! But wait...regular past isn't that
regular. We actually encounter three different regular suffixes.
First of all,
the (regular) verbs that end in a vowel different than e take the suffix
-dde in the past tense; in our temporary list from the previous page, we only find two:
Next group of regular verbs are those that take the suffix
-et (optionally -a, but we'll work only with -et
here). All these already end with an -e in infinitive, so in
practice you just need
to add -t. Let's say for now that this is the case for verbs that
have a k (although the issue is a bit more complicated) just
before the last e in the infinitive form:
|to speak / talk
So there's one regular group left...
