Secondary design goals were to further simplify Esperanto's grammar and vocabulary. When words were phonetically simplified to meet the primary design goal, it became harder to recognize them from their roots, necessitating changes to keep the vocabulary easily learnable. It is also not yet complete, with the vocabulary still being simplified. An allophone is one of at least two alternate pronunciations for a phoneme. As with Esperanto, the accent is always on the penultimate syllable.
Every word is spelled phonemically.
Thus Esperanto is borrowed as Eseperanta . Nouns end in -a . They are not inflected for plural, gender or case. The relationship of case is expressed by prepositions. The comparative is made by using the word pelo , the superlative by supelo .
