'nectar-rich' originates from the combination of 'nectar' and 'rich', where 'nectar' refers to the sweet liquid produced by flowers and 'rich' means abundant or plentiful.

'nectar' comes from the Latin word 'nectar', which was borrowed from Greek 'nektar', meaning 'drink of the gods'. 'Rich' comes from Old English 'rice', meaning 'powerful' or 'wealthy'.

Initially, 'nectar' referred to a divine drink, but over time it evolved to mean the sweet liquid in flowers. 'Rich' has maintained its meaning of abundance.
