Explanation at your level:

This phrase means something was very hard to do. You use it when you worked a lot to finish a task. For example: 'I finished my homework with difficulty.' In Portuguese, we say 'a custo'. It is like saying 'with a big cost of energy'.
You use 'a custo' to show that an action was not easy. It is more formal than just saying 'muito difícil'. When you say 'Ele chegou a custo', it means he arrived, but he was very tired or had many problems on the way. It is a good way to describe hard work.
At this level, you should use 'a custo' to add variety to your descriptions of effort. Instead of always using 'com muita dificuldade', 'a custo' sounds more natural in written stories or formal emails. It implies that the person had to sacrifice something, like time or comfort, to reach their goal. It often appears with the verb 'conseguir'.
'A custo' is an adverbial expression that emphasizes the arduous nature of an achievement. It suggests a process of overcoming resistance, whether internal (like laziness or fear) or external (like bad weather or lack of resources). It's common in news reports and professional contexts to describe difficult negotiations or complex projects that were finally completed.
As a C1 learner, you should recognize 'a custo' as a marker of sophisticated register. It functions as a nuanced alternative to 'a duras penas', focusing specifically on the 'toll' taken on the subject. It requires an understanding of the subtle difference between 'à custa de' (at the expense of) and 'a custo' (with difficulty). Mastery involves using it to convey a sense of gravitas and persistence in formal discourse or literary analysis.
In the realm of near-native mastery, 'a custo' is employed to evoke the philosophical weight of effort. It resonates with the Lusophone concept of 'luta' (struggle) and 'superação'. A C2 speaker uses this phrase to navigate the fine line between describing physical labor and psychological endurance, often utilizing its placement at the start of a sentence to create a dramatic, rhythmic pause that underscores the magnitude of the struggle described.

زمینه فرهنگی

In Portugal, 'a custo' is often linked to the historical resilience of the people, especially in the context of the sea and the 'Descobrimentos'. It carries a sense of stoicism. Brazilians might use 'a custo' in formal news, but in daily life, they often say 'com muito sacrifício' to emphasize the emotional drama of the effort. In Angolan literature, 'a custo' is frequently used to describe the hardships of the colonial era and the subsequent reconstruction of the country. Similar to Angola, it appears in formal speeches regarding national development and overcoming natural disasters like cyclones.
