The English letters Q, W, X and Y do not exist in Esperanto.
The letter Ŭ is only found in diphthongs—Baldaŭ is sounded Bahldow.
The one remaining point to be mentioned is that "AJ" is the same as in By. "OJ" as in Boy.
ALL NOUNS end in O in the nominative singular. Birdo, a bird.
When the direct object to a verb, an N is added to this O. Mi havas birdon, I have a bird.
All nouns form the PLURAL by adding J to the singular. Birdoj, birds. If objective, birdojn.
All ADJECTIVES end in A and agree with the noun in number and case. Mi havas belajn birdojn, I have beautiful birds.
The INFINITIVES of VERBS always end in I. Lerni, to learn. Pensi, to think.
