From an alternative language: This is a redirect from a page name in Portuguese to a page name in English. These words may directly translate or they may be related words, names or phrases.
This redirect leads to its target in accordance with the naming conventions for titles in other languages and can help writing and searches. However, per WP:NOTBROKEN do not replace these redirected links with a piped link.
From a page move: This is a redirect from a page that has been moved (renamed). This page was kept as a redirect to avoid breaking links, both internal and external, that may have been made to the old page name.
