Learn Italian: Lavorerò molto per realizzare l'obiettivo. - I will work a lot to achieve the goal.

In the future tense, regular verbs that end in -are (like lavorare) change their characteristic 'a' to an 'e' before adding the endings. So, the stem becomes lavorer- and then you add the future ending -ò for the 'I' form.

Why does molto stay masculine singular here?

In this sentence, molto is acting as an adverb describing how much you will work (meaning 'a lot' or 'hard'). When molto modifies a verb, it never changes its ending. It only changes to match gender and number when it acts as an adjective describing a noun (like molti libri for 'many books').

Why do we use per before realizzare?

In Italian, when you want to say 'in order to' or express the purpose of an action, you use per followed by the infinitive (dictionary) form of the verb. So, per realizzare translates perfectly to 'in order to achieve' or simply 'to achieve'.

Does realizzare mean the same thing as the English word 'realize'?

Realizzare can mean 'to achieve' or 'to make real' (like an objective or a dream). It is sometimes used to mean 'realize' in the sense of suddenly understanding something, but Italians much more commonly use the phrase rendersi conto or the verb capire for that mental click.
