Learn Italian: Marco pulisce sempre la macchina.

The dictionary form of this verb is pulire (to clean). It belongs to a special group of -ire verbs that insert -isc- before the ending in most present tense forms. For Marco (the he/she form), the ending is -e, so we combine pul- + -isc- + -e to get pulisce.

Do all -ire verbs use this -isc- pattern?

No, only some of them do! Common ones include pulire (to clean), capire (to understand), and finire (to finish). Other common verbs like dormire (to sleep) or partire (to leave) use standard endings without adding -isc-. You just have to memorize which verbs belong to the -isc- group as you learn them.

How do you pronounce the sce part of pulisce?

It makes a sh sound, followed by an eh sound (like sheh). In Italian, any time the letters sc are followed by an e or an i, they combine to make a soft sh sound.

Why does sempre come after the verb instead of before it?
