Synonym discussion
Sense: adjective/1
For sense 1, 'brilliant' is strong everyday praise. 'Excellent' is slightly more formal and fits school or work feedback well, as in an excellent report. 'Great' is broader and more casual, so it works naturally for a great weekend or a great meal. 'Outstanding' sounds more evaluative and suggests being better than others in the same group, such as an outstanding player. 'Superb' is polished and often appears in reviews of food, music, or craft. A brilliant holiday can simply mean you enjoyed it a lot, while an outstanding holiday sounds more judged against a high standard. Compare: 'You did a brilliant job on the poster' and 'The teacher wrote excellent comments on the essay.'
Etymology
'Brilliant' came into English from French 'brillant', meaning 'shining', from the verb 'briller', 'to shine'. It first described things that gave back a strong light, especially cut diamonds. English later extended the word from physical brightness to bright minds, and then to anything judged extremely good. That history helps explain why one word can link light, intelligence, and excellence.
