A variety of definitions exist for the term 'honey', but all cite the role of honey bees in its production.
According to US regulations, 7 USC § 4602(7)1:
In the UK, the Honey (England) Regulations 2015 adopt the EU regulatory definition2:
Interestingly, the UK/EU definition appears to reflect the origin of most commercially available honey (from Apis mellifera specifically), whereas the US definition is more flexible, and (whether intentionally or not) allows for the fact that honey may be produced by different honey bee (Apis) species, not only Apis mellifera.
However, the UK/EU definition allows for honey made from aphid secretions (see honeydew honey) whereas this is omitted from the US definition.
An alternative answer to the question of what honey is, could briefly mention the process, and include what it contains, and may be given as follow:
Beekeepers take the honey made by bees from hives once they can see the honeycomb cells have been capped (sealed) by the bees. Some beekeepers then treat it through heating and filtering before it is stored in jars.
The honey harvested and consumed by humans is made by the honey bee. However, a small number of wasps found in South America also make honey, but not in commercially exploitable quantities. Read more on my page: Do Wasps Make Honey?
Honey is a available in a number of presentations.
Raw honey is simply honey that has not yet been treated by the beekeeper through heating and filtering.

Powdered and granulated honey tend to contain a large number of ingredients other than honey - the key is to check the label of the item you are thinking of purchasing to see what it contains, because they can be quite different.
