Verbs

Note the correlations between the tenses of the infinitive and non-infinitive conjugations (future -o, past -i, present -a)

The verb "to be" is esar. Me esas (I am), Me esis (I was), Me esos (I will be).
You can just say es instead of esas if you feel like it. You use this verb all the time and that's why it has a short form.

To make a negative, just put ne before the verb. Me ne esas (I am not), ne flugas (doesn't fly), ne vidos (will not see).

Replacing -ar with -anta turns the verb into an adjective describing the thing that is doing an action. Fluganta uceli - flying birds. Kantanta viro - a singing man.
Replacing -ar with -inta turns the verb into an adjective describing the thing that has done an action. Fluginta uceli - birds that have flown. Kantinta viro - a man that has sung.
Replacing -ar with -onta turns the verb into an adjective describing the thing that is going to do an action. Flugonta uceli - birds that are going to fly. Kantonta viro - a man that is going to sing.

Replacing -ar with -ata turns the verb into an adjective describing the thing that is having something done to it. Drinkata aquo - water being drunk. Manjata pano - bread being eaten.
Replacing -ar with -ita turns the verb into an adjective describing the thing that had something done to it. Drinkita aquo - water that was drunk. Manjita pano - bread that was eaten.
Replacing -ar with -ota turns the verb into an adjective describing the thing that is going to have something done to it. Drinkota aquo - water that is going to be drunk. Manjota pano - bread that is going to be eaten.

When saying things like "I have eaten," "I had gone," and "I will have sung," you use the endings -abas, -abis, and -abos. Me manjabas la pano (I have eaten the bread), me manjabis la pano (I had eaten the bread), me manjabos la pano (I will have eaten the bread).
