For the perfect tense, we use a past participle. For the conjugation of the past participle, we must distinguish between t-verbs and d-verbs? (just like we did for the simple past?). To establish whether we are dealing with a t-verb or a d-verb, we have to look at the last letter of the verb stem. If this is t, h, f, c, k, s or p, ("pocket fish") it is a t-verb, all other verbs are d-verbs.
past participle = ge + [stem] + t or d
Whether the past participle ends in a -t or -d depends of course on whether the verb is a t or a d-verb?.
| maken
| to make
| stem: maak (t-verb)
| past participle: ge + maak + t = gemaakt
|
| luisteren
| to listen
| stem: luister (d-verb)
| past participle: ge + luister + d = geluisterd
|
In Dutch I have made becomes: ik heb gemaakt .
The ge + stem + t/d rule applies to most regular verbs, but there are also verbs that need an extra or different treatment.
Two points to bear in mind for the past participle:
1. A past participle never ends in double t or double d
If the stem ends in -t we do not add an extra t to the past participle, if a stem ends in -d, we skip the extra d. This is actually not really an exception, if you remember that a syllable never ends in two identical consonants.
| rusten
| to rest
| does not become: ge + rust + t
| but: ge + rust = gerust
|
| bloeden
| to bleed
| does not become: ge + bloed + d
| but: ge + bloed = gebloed
|
2. Prefixes be-, er-, ge-, her-, ont- and ver -
All verbs that start with the prefixes: be-, er-, ge-, her-* , ont-, and ver- do not get ge - before the past participle, because the prefix replaces ge -: the rule for forming the past participle is here: (no ge) stem + t/d.
| infinitive
| in english
| past participle
|
| verdelen
| to distribute
| stem+d = verdeeld
|
| geschieden
| to happen
| stem (no extra 'd') = geschied
|
| betalen
| to pay
| stem+d = betaald
|
| ontdekken
| to discover
| stem+t = ontdekt
|
| erkennen
| to acknowledge
| stem+d = erkend
|
| herkennen
| to recognize
| stem+d = herkend
|
In the category of her-words, there are a few exceptions:
| infinitive
| in english
| past participle
|
| herbergen
| to accommodate
| ge+stem+d = geherbergd
|
| herhuisvesten
| to relocate
| ge+stem (no t ) = geherhuisvest
|
| herstructureren
| to restructure
| ge+stem+d = geherstructureerd
