The _te_ \+ infinitive construction is a typical characteristic of [short subclauses](#/lesson/WordOrder.62). In English, we have short subclauses too. Just look at "He claimed to be a prince", which is short for "He claimed that he was a prince". Where the first phrase consists of one single clause, the latter has two clauses: "He claimed" and "He was a prince".
_Dat_-verbs
The auxiliary verbs below are actually [independent verbs](#/lesson/Verbs.Au02), for the verbs that follow are part of a different clause, a [short subclause](#/lesson/WordOrder.62) to be more precise.
The verbs can also be used in constructions as "I think that.." - hence the name of this category.
beloven\*
_to promise_ | Hij belooft vanaf nu op tijd te komen. | He promises to be on time from now on.
beweren
_to claim_ | Hanneke beweert het te weten. | Hanneke claims to know it
blijken
_to appear_ | De groenteboer blijkt veel te weten. | The grocer appears to know much.
denken
_to think_ | Piet denkt het te zullen doen. | Piet thinks that he will do it.
hopen
_to hope_ | Loes hoopt erbij te zijn. | Loes hopes to be there.
lijken
_to seem_ | Hidde lijkt het leuk te vinden. | Hidde seems to like it.
menen _to mean_ | Ik meende haar te horen. | I thought I heard her.
schijnen
_to seem_ | De burgemeester schijnt het goed te keuren. | The mayor seems to approve of it.
wensen\*
_to wish_ | Mijn broertje wenste koning te zullen worden. | (lit) My little brother wished to become king.
(\*) beloven and wensen also appear in the list of [om-verbs](#/lesson/Verbs.Au11).
These verbs can also precede a normal [subordinating clause](#/lesson/WordOrder.55) when they are followed (like in English) by _dat_ (that):
beloven
_to promise_ | Hij belooft dat hij vanaf nu op tijd komt. | He promised that he would be on time from now on.
beweren
_to claim_ | Hanneke beweert dat ze het weet. | Hanneke claims that she knows it.
blijken\*
_to appear_ | Het blijkt dat de groenteboer veel weet. | It appears that the grocer knows a lot.
denken
_to think_ | Piet denkt dat hij het zal doen. | Piet thinks that he will do it
hopen
_to hope_ | Loes hoopt dat ze erbij zal zijn. | Loes hopes that she will be there.
lijken\*
_to seem_ | Het lijkt erop dat Hidde het leuk vindt. | It looks like (it) that Hidde likes it.
menen
_to mean_ | ik meende dat ik haar hoorde. | I thought that I could hear her.
schijnen\*
_to seem_ | Het schijnt dat de burgemeester het goedkeurt. | It seems that the mayor approves of it
wensen
_to wish_ | Mijn broertje wenste dat hij koning zou worden. | (lit) My little brother wished that he became king.
Note:
- Regarding _blijken, lijken en schijnen:_ just like in English, when these verbs are followed by _dat_, the subject can only be _het_ (it).
Het blijkt dat... | It appears that...
Het schijnt dat... | It seems that...
Het lijkt erop dat... | It looks like it that...
You cannot say "she appears that...".
_Dat_-verbs in the perfect tense
For the perfect tense, we use a past participle. Normally, we replace a past participle by an infinitive, if it serves as an auxiliary verb. See also [Past participle turning into an infinitive](#/lesson/Verbs.Au05).
Let us take the sentence "Hij belooft vanaf nu op tijd te komen", which means "He promises to be on time from now on." If we set the sentence in the pluperfect tense, we would expect to get "Hij heeft beloven vanaf nu op tijd te komen." After all, the auxiliary verb _beloven_ should not be able to support _komen_ in the form of a past participle (which would have been _beloofd_).
However, in this case we do use a past participle. This not really an exception to the rule that a past participle cannot serve as an auxiliary verb': As a _dat_-verb, _beloven_ does not really act as an auxiliary verb for _komen_ since they are located in two different clauses: _Beloven_ in the main clause and _komen_ in the short subclause.
Hij heeft beloofd vanaf nu op tijd te komen. | He has promised to be on time from now on.
Hanneke heeft beweerd het te weten. | Hanneke has claimed to know it.
Piet had gedacht het te zullen doen. | Piet had thought that he will do it.
