When the topic "past participle" comes up, teachers using the audiolingual method undoubtedly have a certain advantage over the "traditional" method of instruction. The student in the audio-lingual class has been trained to recognize both the existence and the functional load of stress. Such training can be fully utilized in determining whether the past participle of a particular verb has the prefix ge-. Although we are concerned here with the presence or lack of ge-, a few remarks about the stem and suffix of the past participle are in order. Weak verbs regularly retain the stem vowel of the infinitive (exceptions: brennen, nennen, kiinnen, etc.). The suffix -t is added to the verb stem. -et is used when the stem ends in -d, -t, or certain consonant combinations (e.g. 6ffn-, etc.). Strong verbs suffix -en to the participle stem. The vowel of this stem (and occasionally consonant changes, e.g. -nommfrom nehmen) must be learned,' either by rote or in terms of the familiar Ablaut-series.
