Learn Italian: Studio molto.

In Italian, you often drop subject pronouns like io (I). The verb ending already tells you who is doing the action. Studio comes from the regular -are verb studiare (to study). You chop off the -are and add -o for the "I" form. Since studio can only mean "I study," adding io is not necessary!

The dictionary says "to study" is studiare. Why does studio have an "i" before the "o"?

When you conjugate a regular -are verb, you remove the -are to find the root or stem of the verb. For studiare, the stem is studi-. Then you add your ending. For "I", you add -o, which gives you studi- + -o = studio. The "i" was already part of the word's stem!

Will molto ever change its ending to molti or molta in sentences like this?

Not in this case! Here, molto describes the verb (how much you study). Words that describe verbs are called adverbs, and they never change their endings. Molto only changes its ending to molti or molte when it describes a noun (like saying molti libri for "many books").

Does molto always go after the verb?
