Question

What is a definition of irregular verb in Spanish?

Answer 1

A verb that does not conjugate according to normal rules.

Explanation:

For example the verb Ser (to be), which is a very common word that is used all the time, is very irregular. In the present tense it is

Soy, Eres, Es, Somos, Sois and Son

However, a normal verb has these endings in the present tense;

Corr`color(red)(o)`, Corr`color(red)(es)`, Corr`color(red)(e)`, Corr`color(red)(emos)`, Corr`color(red)(eis)`, Corr`color(red)(en)`
