On its own
褒 is literary; in modern use it almost only appears in compounds, especially the antonym pair
褒贬 (bāobiǎn, 'praise and disparagement') and the linguistics terms
褒义词 (bāoyìcí, 'word with positive connotation') vs
贬义词 (biǎnyìcí, 'word with negative connotation'). Knowing this pair is essential for talking about word choice.
