How are the French and Italian languages alike?

They are similar in the accents.

The accents are the same in writing but their use is completely different . Where in French they are almost always used to change the pronunciation of a vowel in Italian they generally change where the stress falls in a Words (stress generally falls on the second last syllable in Italian unless an accent dictates otherwise).

Their vocabulary is very similar, although Spanish is pronounced phonetically like Italian where French is not, the vocab itself is more similar between Italian and French. Spanish and Portuguese are more closely related (due to relations in the past).

Also verb formation, and types of verbs are very similar (indicative, imperative, subjunctive, conditional) also the type of conjugation one chooses changes the mood of the verb in question.

As a student who has studied Spanish, French, and Italian. French and Italian are more closely related that it would sound.
