Well, yeah, sorry, i made a mistake.Not ALL verbs end in -er for infinitive. In fact, there are 3 terminations possible for a verb.
-ar (E.g: "Falar" = "To Speak")
-er (E.g: "Comer" = "To eat")
-ir (E.g: "Fugir" = "To run" (away)/"Escape")
Each one is the equivalent of TO in english.
And this is important because it will affect how verbs end when conjugated in different times.
But lets focus now on the "you","he", etc...
There are "singular" (for one person) and "plural" (for multiple)
There are 3 'persons' in singular
'Eu' = "Me"
'Tu' = "You"
'Ele' (♂) /'Ela' (♀) = "He"/"She"/"It"
3 'persons' for plural
"Nós" = 'We'
"Vós"/"Voces" ("voces" its not official, but its the same as "Vós") = 'you'
"Eles" = 'they'
Now, if you haven't noticed yet, there are 2 "You". This is mainly because the plural distinction between the people that Portuguese people do, but also because the formal version,"você", and the informal version, "tu". We treat someone with respect with "voce", while we treat a friend with "tu".
So, a regular verb ended in -ar, conjugated in present simple ('presente' in portuguese) is like this:
Verb 'FALAR' (speak)
eu falo
tu falas
ele/ela fala
nós falamos
vós falais
eles/elas falam
As i told you before, the fact that it ends in -ar is important. Lets see how/why seeing another -ar terminated verb.
Verb 'ANDAR' (walk)
eu ando
tu andas
ele/ela anda
nós andamos
vós andais
eles/elas andam
Did you notice it? The similarity? ;) We just conjugated in present, but the similarities apply for other times as well.
Taking the case of 'to be'... Well, its an irregular verb, so yes, its just as crazy, there are no similarities between verbs, and its different for each time.
Verb 'SER' (to be):
eu sou
tu és
ele/ela é
nós somos
vós sois
eles/elas são
To see how crazy this verb is, let's compare with a regular -er ended verb
Verb 'COMER' (eat):
eu como
tu comes
ele/ela come
nós comemos
vós comeis
eles/elas comem
Somewhat different, huh? But wait!! There's more: Now the past ("PASSADO") versions of these verbs:
Verb 'SER' (to be):
eu fui
tu foste
ele/ela foi
nós fomos
vós fostes
eles/elas foram
Verb 'COMER' (eat):
eu comi
tu comeste
ele/ela comeu
nós comemos
vós comestes
eles/elas comeram
(this is the normal endings for -er verbs)
WOW? DAFUQ?
Well, this is just for -er/-ar present verbs. Its still missing the past/future versions. But that's for tomorrow
