With regular verbs, the past participle usually begins with the prefix ge-; then comes the verb root, followed by a -t at the end.
If the verb root ends in -t or -d, an additional e is added. This extra e is also added after a cluster of consonants. Often, you will be able to identify when an e is necessary, as without it, the word would be hard to say.
Some verbs make the past participle without ge-:
- Verbs which end in -ieren
- Verbs with inseparable prefixes, i.e. be-, ent-, er-, ver-, zer-
