великого
"Великого" means "great" or "of great" in English, typically in the genitive or accusative case.
The word 'великого' is used in its genitive singular masculine form, qualifying a noun ('художника') that implies distinction or importance.
Это картина великого художника.
This is a painting by a great artist.
Here, 'великого' takes a genitive singular neuter form to modify an abstract noun ('терпения'), often showcasing a commendable or noteworthy quality.
Он показал пример великого терпения.
He demonstrated an example of great patience.
In this sentence, 'великого' again functions as an adjective in the genitive singular masculine form, describing a recognized intellectual figure ('философа').
