Is there no end to the suffering? It's not enough that we have to learn to conjugate 3 different verb types (the ar, ei & ir endings). There is yet another group: the Portuguese ~or verbs!
Sim, e não.
The good news is, there are only a few of these actually used and: their conjugations (in all tenses) is virtually identical!
(1) pôr to put, place
Don't confuse this with por! This is the most common ~or verb. It's used mostly in the present and the (simple) past tenses. Like this:
Here's the complete conjugation of the verb pôr.
All of the other ~or verbs are just inventions of pôr.
(2) supor to suppose
This is used quite a lot!
You'll also hear it's past participle: suposto(a).
(3) dispor to dispose, incline, place into order
This verb is difficult to learn as there are several meanings. The one you're likely to encounter is, at your disposal and, willing (the past participle).
(4) propor to propose
You'll also hear it's past participle: proposto(a).
It's adjective form is very common too: a proposta
(5) expor to expose, exhibit
You'll also hear it's past participle: exposto
(6) compor to compose
You'll also hear it's past participle: composto
Less common Portuguese ~or verbs include:
sobrepor, opor, antepor, contrapor
