Before you choose a hard synonym, ask which of its six jobs the word is doing: difficult, tough or challenging for tasks, firm or solid for objects, harsh or strict for people, and diligently for working hard. A rock and a math test are both hard, but they share no other synonyms.

How tough is it: tricky up to brutal
For tasks, the scale climbs in five steps. Tricky means it needs care or a clever move. Difficult is the neutral middle. Demanding says it takes steady energy over time. Grueling wears you out, like a long climb in the heat. Brutal is informal and the most extreme.
Arduous and laborious sit near grueling but sound formal. Laborious often hints that the work is slow and dull, not just heavy.

As an adverb, hard follows the verb: work hard, try hard, push hard. Swap it with diligently, intensely or the casual flat out.
