51. When the verb in a sentence precedes its subject, English often uses
an introductory particle, such as "there," "it." In Esperanto no such
particles are needed:
Estas floroj sur la tablo, there are flowers on the table.
Estis Johano, ne Alfredo, en la gxardeno,
it was John, not Alfred, in the garden.
Estas domo en la kampo, there is a house in the field.
Estis mi, it was I.
