The articulated prepositions

What an “articulated preposition” is (and why Italians use it)

Italian often combines:

• simple preposition (di, a, da, in, su) + definite article (il, lo, la, l’, i, gli, le)
• into one word: del, al, dal, nel, sul…

Think of it as English “of the / to the / from the / in the / on the” written as one unit in Italian.

How to build it in 3 steps (your quick method)

1. Choose the preposition: di / a / da / in / su
2. Find the correct definite article for the noun (il, lo, la, l’, i, gli, le)
3. Merge them (use the table): di+il → del, a+la → alla, in+l’ → nell’, etc.

Self-check: If in English you naturally say “___ the …”, Italian often needs the articulated form.

Pick the right article first (the part that causes most mistakes)

The article depends on the noun that follows (gender + singular/plural + starting sound).

Tip: If you know the noun with its article (e.g., il mercato), you can build the articulated form fast: a + il → al mercato.

Meaning: what these forms usually express

• di + article = of the / about
  • la casa dei miei amici = the house of my friends
  • parliamo del tempo = we talk about the weather
• a + article = to the / at the
  • andiamo al mercato = we go to the market
  • sono all’ufficio = I’m at the office
• da + article = from the
  • prendo l’ombrello dalla macchina = I take the umbrella from the car
  • il vento arriva dal nord = the wind comes from the north
• in + article = in the
  • molte nuvole nel cielo = many clouds in the sky
  • lavoro nell’ufficio = I work in the office
• su + article = on the
  • la giacca sulla sedia = the jacket on the chair
  • il sole splende sulle montagne = the sun shines on the mountains

The forms that look similar but mean different things

• del = di + il = of the
  • parliamo del progetto = we talk about the project
• dal = da + il = from the
  • torno dal lavoro = I come back from the office/work

Self-check: Ask yourself: is it “of” (ownership/topic) or “from” (origin/movement)?

When you do NOT merge (important exceptions)

• per, tra, fra + article: no merge
  • per il centro (not pel)
  • tra la riunione e il pranzo
  • fra gli uffici
• con: only merges with il and i
  • col direttore (= con il direttore)
  • coi colleghi (= con i colleghi)
  • With other articles, keep it separate: con la collega, con gli amici

Note: In modern Italian, con il / con i is also common and always correct; col / coi is simply a shorter option you will see.

Fast decision guide (use this before you answer)

1. Do I need “the” in English? If yes → probably articulated.
2. Which preposition fits the meaning? di / a / da / in / su
3. What’s the noun’s article? (il/lo/la/l’/i/gli/le)
4. Merge using the table: preposition + article → one word

Common pitfalls to avoid (A1 focus)

• Don’t write them separated in normal Italian:
  • da la → dalla
  • in il → nel
  • su il → sul
• Watch l’ before vowels:
  • all’ufficio, dell’ombrello, nell’auto
• Remember the “special” masculine forms:
  • allo studio, nello zaino, sullo schermo
  • Plural: agli amici, negli uffici, sugli scaffali
