How about we first conjugate the verb in question? Come on:
I brake
you brakes
he brakes
We we brake
You freais
they brake
Did you notice the particularity? Only the first and second person plural, that is, those called arrhizotonic forms, whose stressed syllable appears outside the stem, they are not demarcated by the presence of the vowel “i”: freamos / brakes. Thus, we can say that, when dealing with these grammatical persons (first and second plural), the verb presents itself as regular.
In other grammatical persons, as noted, the vowel in question (i) appears demarcated - a fact that attributes to the verb the condition of irregular. Thus, it is worth saying that such occurrence is manifested in the present tense and in the tenses derived from it, that is, in the present tense of the subjunctive:
that I brake
that you brake
let him brake
that we free
that you free
that they brake
And in imperative mode, both negative and affirmative:
Affirmative
you brake
brake him
let us free
brake you
they brake
Negative
don't you brake
don't brake you
we don't free
do not free yourselves
don't brake you
In the face of such elucidations, when you hear someone out there saying that a certain person “broke on” abruptly, remember the postulates highlighted here. That is, actually he (or she) doesn't she braked, but she did.
