All verbs which form the preterite without the addition of an ending are
_strong verbs_. There is usually a change of vowel. The termination of the
past participle in _-n_ or _-en_ is a sure indication that a verb is
_strong_. Some verbs show forms of both conjugations.

A complete list of _strong_ verbs cannot be given here, but a few of the
most common will be given, together with a few _weak_ verbs, in the use of
which mistakes occur.
