Example: traducir translate - tradu zco conocer know - cono zco but: hacer make - hago mecer cradle, rock - mezo cocer cook - cuezo The exceptions to this are the verbs hacer, mecer, and cocer.

In order to preserve the pronunciation, we have to change the last consonant of the word stem for some -er/-ir verbs in the 1 st person singular.Įxample: c becomes z → me cer cradle, rock - me zo g becomes j → co ger take, lift - co jo gu becomes g → distin guir distinguish - distin go qu becomes c → delin quir commit (a crime) - delin coįor verbs that end in - ducir or with a vowel + cer, we add a - z before the - c in the 1 st person singular.
