Complex Tenses
So far, we have covered how to form infinitives, the three simple tenses, commands, and conditionals. We will now cover how to use participles to create more complex tenses.

By combining a participle with a form of the verb "esti" ("to be"), you can create a verb combining two tenses. Look at the chart below.

You will notice that many of these combinations have awkward English translations. Though all of these combinations are acceptable Esperanto, a rewording would be appropriate when translating them into English.

Remember that the three simple tenses should be used whenever possible. These combinations should only be used when the alternative would cause ambiguity.
