Learn Portuguese (Portugal): O artesão está lentamente a soprar a bolha. - The artisan is slowly blowing the bubble.

While beginners often learn the continuous tense (estar a + infinitive) as an unbreakable block, you can actually place adverbs like lentamente between the auxiliary verb (está) and the preposition (a). You could also put it at the end (está a soprar a bolha lentamente), but splitting the verb phrase is very natural in European Portuguese.

What is the plural of artesão?

The plural is artesãos. Nouns ending in -ão are famously tricky because they can pluralize to -ãos, -ões, or -ães. There is no strict rule to guess it, so it is best to memorize artesãos when you learn the singular word.

Is bolha used for other types of bubbles?

Yes! Besides a literal glass or soap bubble, bolha is the everyday word for a blister on your skin (like uma bolha no pé for a blister on the foot). It is also used for financial bubbles, like uma bolha imobiliária (a housing bubble).
