When you use it
Reach for this when the subject is he, she, it or a single name and the verb describes a habit or routine, such as 'Samy helps his father'.
Watch out
Do not add -s after I, we, you or they: write 'they walk', not 'they walks'. Verbs ending in -sh, -ch, -s or -x take -es (wash, washes), and a consonant before a final -y changes the y to -i before -es (carry, carries).
