Princely

Strikingly generous, splendid, or large enough to evoke royal wealth.

Reach for it when praising a gift, sum, or setting for exceptional generosity or magnificence

A princely donation secured the observatory's public nights for another decade.

• playful

  royal

  when informal exaggeration can evoke abundance fit for royalty

  not when Royal risks a literal monarchy reading unless the exaggeration is obvious.

• warm

  generous

  if willing giving matters more than the size or splendor

  not when Generous covers modest acts and lacks the scale of princely.

• professional

  handsome

  for a substantial amount that deserves approving notice

  not when Handsome is idiomatic with sums and may be ambiguous elsewhere.

• formal

  lavish

  when generosity or expenditure greatly exceeds the ordinary

  not when Lavish can imply excess and is not inherently dignified.

• formal

  munificent

  when a gift is exceptionally liberal in size

  not when Munificent is rare and applies more precisely to giving than surroundings.

• literary

  magnificent

  for impressive grandeur that inspires admiration

  not when Magnificent says little about generosity and can describe natural scenery.

• meager
• stingy
• paltry

• princely sum

  The auction raised a princely sum for the mountain rescue service.

• princely gift

  A princely gift of instruments equipped every school in the district.

• princely hospitality

  The hosts offered princely hospitality without making the visitors feel indebted.
