I have been practicing and learning other languages, eating more healthily, doing
exercises and being more talkative, which is funny, because I used to be a shy person.😅
Olá Barbara, muito bem.
Another is singular. Other is used as an adjective of languages and adjectives are never plural.
Healthier is an adjective used to describe an object. Healthily is an adverb to describe the verb or action of eating.
Keep practicing! Simón.
