Learn Portuguese (Portugal): Ao falar com o subgerente, percebi a crise. - Upon speaking with the assistant manager, I understood the crisis.

The prefix sub- indicates a lower hierarchical position, meaning "under" or "below". While gerente is the manager, a subgerente is the person directly below them. In English, we usually translate this hierarchical relationship as "assistant manager" or "deputy manager" rather than "sub-manager".

Are there specific spelling rules for attaching sub- to a word like gerente?

Yes! With the prefix sub-, you generally only use a hyphen if the following word starts with b, h, or r (for example, sub-região). Because gerente starts with a g, the prefix attaches directly to form the single word subgerente without a hyphen.

Why use Ao falar instead of a phrase like Quando falei?

The structure ao + infinitive (falar) translates nicely to "upon speaking" or "at the time of speaking". It is a very common and elegant way to show that two actions are closely connected in time. Quando falei (When I spoke) would also be correct, but ao falar emphasizes the immediate connection between having the conversation and realizing the crisis.

Is percebi a false friend here?
