Some words are easy in Italian and some others are a little complicated. Here's a verb we use a lot but that is kind of tricky to use: accorgersi (to notice, to realize).
Let's take it apart to make some sense of it. Hint: It is reflexive, and while some verbs can be both normal and reflexive, this one is always reflexive.
In a recent episode of La Ladra, a guy wants his car taroccata (rigged) (we talked about the verb taroccare in this lesson). The mechanic tells the guy that he won't even notice he's going 300 kilometers per hour. Usually, we notice something, so very often, since accorgersi is reflexive, we have both a direct and an indirect object pronoun in the sentence. When that occurs, we have to deal with those pesky particles that can attach themselves to the verb in different ways. For more on this, have a look at these lessons.
In the following example, we can see that the verb is conjugated in the second person singular (the mechanic is talking to his customer).
Co' [romanesco: con] questa c'arivi [ci arrivi] a trecento che manco te n'accorgi.
With this one, you don't even notice it when you get to three hundred.

The infinitive form has the impersonal si connected to the verb — accorgersi, but when conjugated, the reflexive verb accorgersi gets separated into two parts — the root of the verb (accorgere) and the person onto whom it reflects, in this case, te (to you). Then there is an n which is a contraction of ne (of it, to it). In order to understand better how accorgersi works, we might translate it as "to become aware of." Here, there is the preposition "of."
By the time to get to three hundred [kilometers an hour], you will not even be aware of it.
"Of it" is represented by ne (in this case contracted into n').
In the following example, however, we have the past tense. In Italian, it's the passato prossimno formed with the auxiliary verb essere (to be) and the past participle, accorto. When you conjugate reflexive verbs in the past tense, you must use essere as your auxiliary verb.
Gira e gira, ai vertici dell'Olivetti, non c'è spazio che per uno di famiglia. Lo so, me ne sono accorto. -Ecco.
At the end of the day, in the upper echelons of Olivetti, there's no room for anyone but a family member. I know, I noticed that. -That's it.

Me is the indirect pronoun (to me)
Ne is another indirect pronoun (of it, about it)
Accorto is the past participle of accorgere.
Let's look at an example without this particle ne. Here, it's not necessary because we have nulla (nothing) as an indirect object preceded by the preposition di. We have the auxiliary verb essere. The reflexive particle si is contracted and refers to the third person singular reflexive pronoun.
Guardi, non s'era accorto di nulla.
Look, he hadn't noticed a thing.Play Caption
You made it this far, good for you! If the verb accorgersi is too difficult for you at this stage of the game, you can also use the verb notare, a nice, simple, transitive verb.
Durante il viaggio avete notato qualcosa di strano? Pensateci bene, ah.
During the trip, did you notice anything strange? Think about it carefully, huh.

To say the same thing with accorgersi, it would take a few more words:
Vi siete accorti di qualcosa di strano?
Qualcuno si è accorto di qualcosa di strano?
Did you notice anything strange?
Did anyone notice anything strange?
For even more about reflexive verbs, with charts. Here's a great resource.
If you do a search on Yabla with accorgere, you won't find much, nor will you find much with accorgersi. But if you search the past participle accorto (masculine), accorta (feminine), or accorti (plural), you will find numerous examples. Now that we have taken the verb and its particles apart, you can start getting a feel for this useful, but complex verb. Hopefully, picking out the verb and its accessories and then repeating them will be helpful to you.
Attenzione: There will also be some constructions we haven't covered here, such as in the following example. Suffice it to say that it involves the third person impersonal pronoun si with a reflexive verb in the passato prossimo (present perfect) tense. It's pretty advanced and a lot to absorb, and so we'll confront this in a future lesson.
Quando si è sistemata la piazza nel millenovecentonovantuno, ci si è accorti che il palombaro, cioè questa grande cisterna, era colmo fino all'orlo.
When the piazza was renovated in nineteen ninety-one, they noticed that the "palombaro", that is, this large cistern, was full to the brim.
