I have pushed both and also added two new rules:
1) topos de gama > topo de gama
2) premio > prémio
The second one works like this:
"Vem receber O TEU/MEU/SEU/VOSSO/NOSSO PREMIO"
and it suggests to replace "premio" with "prémio".
However, "premio" is not in the Minho University speller, so I added it to the spelling.txt but it will only work in the stand-alone tool and in the browser add-on since I believe that LanguageTool can't overcome the real speller in LibreOffice/OpenOffice.
I checked for "premio" in Priberam and MS Office 2016 and it is a valid word, the verb "premiar" (on Priberam site (FLIP on-line) you can select the conjugate option and write there "premiar" and it will appear in the list).
To be even more sure, I right-clicked on MS Office 2016 and saw it has several synonyms.
