Put the verb in brackets into the positive form of the present simple.
You breakfast every morning. (eat)
Remember that for "he", "she", "it" we add the ending -s or -es to form the present simple.
Have changes to has.
Everything else remains in the base form.
With the endings -s, -ss, -sh, -ch, -x, -z, -o, we use -es.
If the verb ends at -y and there is a consonant before -y (like in cry or study), -y changes to -ies.
