The verb costare ("to cost") works in Italian exactly like its English equivalent. We conjugate it according to the gender and number of the noun it refers to.

But Italian verbs are divided in 3 patterns -are, -ere, -ire, distinguished by the endings of the infinitive form (in its infinitive form, a verb has no subject and isn't conjugated):
To conjugate a verb ending in -are, first you remove the letters -are from the infinitive, which leaves you with the stem:

infinitive: COSTARE (to cost)
stem: COST-

To the stem, add the appropriate ending -o, -i, -a, -iamo, -ate, or -ano according to the subject.

*An important element of verbs is stress. The stress in both singular forms and the third person plural is on the vowel of the verb's stem, while the stress of the first and second plural person is on the theme vowel (in this case, -a-), just as it is in the infinitive.

Please note that in Italian, only vowels at the end of a word can have a written accent mark: this indicates that the stress is on the word-ending vowel.

English also has a different verb ending depending on the subject ("I eat", "you eat", "he / she / it eats"...) but you always must state the subject. In Italian, the subject pronouns are redundant, so they often are omitted.
