How to spell please - Ukrainian spelling. History
There are several reasons why "please" is written separately.
Firstly, this is an evolution from the expression "be kind". Over time, "be kind" has been shortened to "be", but this does not make "be" a particle.
Secondly, "be" is a verb in the imperative form, and "kindness" is a noun in the nominative case.
Thirdly, all authoritative Ukrainian dictionaries, such as the Dictionary of the Ukrainian Language in 11 volumes, record the spelling of "please" separately.
Finally, according to the Ukrainian spelling rules, the particles "be-", "not be", "because-", "but-", "-then", "-even", "-indeed" are written with a hyphen, but "please" does not fall under this rule, as "be" here is not a particle.
