Italian fuses a small set of prepositions directly onto the definite article that follows them, producing a single contracted word instead of two separate ones. Di (of) plus il (the) becomes del. A (to/at) plus la (the) becomes alla. Da (from) plus il becomes dal. In (in) plus la becomes nella. Su (on) plus il becomes sul. These fused forms, called preposizioni articolate, are the standard, required shape of ordinary written Italian, not an occasional stylistic flourish, and they're common enough in news writing that they're worth learning as their own pattern rather than re-decoding one at a time, word by word, every time one shows up.

Why a sentence full of familiar words can still stall

You know il, la, and di individually. You know most of the separate words in an Italian news sentence. And a sentence like "il costo dell'energia è salito nel mese scorso" can still stall you, not because any single word is unfamiliar, but because dell' and nel don't look like the words you learned in isolation. That's not a vocabulary gap, and it isn't a sign you've missed something basic. It's just that these particular words were never taught to you in the form Italian actually uses them in.

The fusion happens across five common prepositions (di, a, da, in, su) crossed with the six forms of the definite article (il, lo, la, i, gli, le), which is why the set of resulting contractions looks larger than it actually is once you see the pattern:

  • di + article: del, dello, della, dei, degli, delle (of the)
  • a + article: al, allo, alla, ai, agli, alle (to/at the)
  • da + article: dal, dallo, dalla, dai, dagli, dalle (from the)
  • in + article: nel, nello, nella, nei, negli, nelle (in the)
  • su + article: sul, sullo, sulla, sui, sugli, sulle (on the)

Before a word starting with a vowel, the article itself often elides further, which is where forms like dell'aumento (of the increase) and sull'economia (on the economy) come from: the apostrophe is standing in for a vowel that got dropped, not marking anything new.

Why apps rarely drill this the way news needs it

Introductory courses and app exercises usually teach di, a, da, in, and su as separate words early on, then teach il, lo, la, i, gli, and le as separate words in a different lesson, and often don't spend much time explicitly drilling the fused forms as their own vocabulary set. You end up able to recognize del and nella individually if you're told what they mean, but not automatically, the way you recognize il or la on sight. Real news writing doesn't wait for that automaticity to develop. A single ordinary sentence, "il costo dell'energia è salito nel mese scorso," stacks two of these contractions before you've even reached the verb, and if neither one is instant for you yet, the sentence stalls twice in a row.

Reading past them faster

The fastest way to build recognition is treating the contracted forms as a short, closed list to drill directly, rather than continuing to mentally decompose them into "di plus il" every time you meet one. There are only thirty common forms across the five prepositions, and once del, della, nel, nella, sul, sulla, and dell' are instant on sight, most of a real news sentence's structural weight stops slowing you down.

A second habit that helps specifically with news text: these contractions cluster heavily around topic-introducing phrases, del governo (of the government), nella regione (in the region), sul mercato (on the market), because news writing constantly locates events within an institution, a place, or a domain. Noticing that pattern, rather than treating each occurrence as a fresh puzzle, turns the contraction from an obstacle into a reliable signal that a place, institution, or topic is about to be named, which is useful information in itself.

What this looks like over a few weeks of real reading

The contracted prepositions are genuinely one of the faster wins available in Italian reading, because the set is small, closed, and repeats constantly, unlike vocabulary in general, which keeps expanding the more you read. Most learners who deliberately drill the thirty common forms, rather than waiting to absorb them passively, notice a real difference in reading speed within a couple of weeks, simply because so much ordinary Italian prose leans on them.

Mundo doesn't have a dedicated Italian hub yet, so this article leads into the same general reading feed that covers every language the product supports today, not a page built specifically for Italian readers. That's worth stating directly rather than glossing over. The Italian text inside that feed is unedited, current news writing, exactly the register where del, nella, and sull' show up on nearly every page, which makes it a reasonable place to put the pattern above into practice.
