The compound period is the sentence that has two or more verbs.
Example:"They fight a lot, that's why stay of punishment".
There is still the period composed by coordination (consisting of two or more sentences that are independent of meaning from each other) and the period composed of subordination (when the main clause is completed by one or more subordinate clauses).
It consists of the time when a woman is at the peak of her fertility, when her ovaries produce and release eggs that can be fertilized when they come into contact with sperm.

Phase in which Brazil was governed by regency (1831 – 1840), when the then emperor of the country, D. Pedro I, abdicated his post.
The successor to the throne would be D. Pedro de Alcântara (son of D. Pedro I), but he was only 5 years old, so, according to the Brazilian Constitution at the time, the country should be governed by regency until D. Pedro II of Brazil reaches the age of majority to govern.
During this period, Brazil had five main regency: Provisional Threesome (1831), Permanent Triangle (1831 – 1835), One of Feijó (1835 – 1837), Interim of Araújo Lima (1837) and One of Araújo Lima (1838 – 1840).
The Regency Period came to an end with the approval of the anticipation of the majority of D. Pedro II for the Federal Senate, an episode that would become known as the Coup of Majority. Thus, in 1840, at the age of 14, the emperor began his reign.
